    For the most part people come to FM Forums seeking advice or assistance. If given a little thought, your topic can really engage the reader to want to assist you in finding the best answer or solution. Step 1: Choose Wisely! By first looking at the topical nature of the forums you can see there are many different forums that cover a wide range of discussions. By way of self-curating the site, try to choose a forum that covers the intent of your topic. We realize that some items cross boundaries and that is ok, just choose a forum that fits the spirit of your topic. If it's wrong a moderator will move it to a forum that best suits the conversation. Step 2: Titles, Names, & Tags Be terse but informative. With your topic title, encourage your reader to want to read your topic. Don't be needy or demanding with "please help" post titles. We realize you've hit a brick wall or may be very frustrated or have a demanding boss. But take a breath - it will be ok. Then compose a topic title that draws them in. Add a tag or two, they will appear next to the topic, it can just be a simple word or phrase that tags the post to some FileMaker-centric topic. Step 3: No Need for Apologies It is not necessary to start your post with an apology to the reader regarding where you are posting or your current understanding of a topic. We are pretty nice here and won't fault you for trying. Step 4: Prerequisite In order for your reader to provide the best response, make sure your profile has been updated with the platform and version of FileMaker that you are using. Otherwise we will assume you are using the most current versions, and the advice given may not work in older versions. If your post is specific to a version / platform / deployment please inform the reader — we don't necessarily need your computer specs, just enough background so that the reader can envision your environment. Step 5: Goals Stating your desired goals, and what you are attempting to achieve in a simple statement will aid the reader as they read further in to the details of your conversation. Step 6: What have you tried? Outline your process and steps you have taken, to get to you the point you are at. It doesn't have to be overly verbose, an essay isn't necessary. Step 7: Format for Emphasis Use the WYSIWYG editor to format text as needed to provide details. You can reference generic terms such as table::field or use your own nomenclature but if the context dictates provide the reader clarity what things may mean if they would not be apparent to someone outside your organization, or industry. this is code from a calculation bullets lists Step 8: Pictures & Sample Files Admit it, you know you miss Show & Tell from kindergarten. Re-live a past life by providing a screen image of your solution. Provide the reader information and context. Use third party tools to draw arrows on your image if needed. Can you send a clone of your solution? - If you do please make sure confidential data is removed, and your boss says it is ok. If you are modifying a commercial version of software that you have purchased — we request that you not do post a clone of these files; as that would be most likely against your terms of service. In that case you can make and post a sample file that recreates the issue you are having. Step 9: A Sense of Humor Keep your sense of humor, and don't forget to smile. The site is visited by members of all skill levels, many are full time developers and consultants and generously volunteer their time and energy to the site. When the occasion calls for it give them your gratitude . A little levity never hurts. Also keep in mind that American English is not everyone's native language -- some things may not translate. If English is not your first language, just do your best. We really appreciate this! It gives us a little spring in our step.

    Version 1.0.0


    A single table might have up to four layouts to present its data: List view (for quick reviewing of records)Print view ( a black & white view for printing)Search form ( holding all the fields in the table Users can search)Detail view (form layout used for editing a record)We've all known for years that we can hide things in sub-summary parts and only display them if properly sorted but now in 14, you can potentially use a single layout for list , searching and editing. In 14, navigation bars allow scrolling in form view and we can take advantage of this by using the Title Footer (or Title Header) to hold our 'form'. A simple switch from list view to form view can provide Users all the fields they need. The title footer can hold portals, tab controls and anything else you would place on an editing or find layout. Related records placed in the Title Footer are not fetched until switching to form view so they have no weight until displayed (just like popovers, tab controls and sliders). In the attached sample, layout triggers assist by switching to form view if in find mode and switching back to list view after a find. I have hidden the list view fields and labels when in form view to simplify the view. The benefits? Less layouts in a solutionLight weightNo need to switch layouts (which might fire triggers)Endlessly scrollable form view (not limited like popovers and sliders)Potential issues? Yes. The header is only one line tall in my sample (holding the list's labels). If you need a vertically-tall header for the list view then this approach might provide too much 'unavailable' space at the top. And switching the process later would not be simple task.I hid the header labels and fields in the list which makes it a bit more work to design (although minimal). You might wish to let them display and only provide additional fields below. This is just another useful, simple tool for our toolkits. BTW, I have specified 'not applicable' on the FM version because 14 hadn't been added as an option yet. Also, this new forum software doesn't allow a title or subject - only accepts a valid file name.

    Ya know, when you rate people with negatives, they will stop assisting you. Wouldn't you in their place? Why should we risk responding just to get slapped for it if you simply don't care for our response? You are judging whether our answers are right or wrong and you know very little about FileMaker. Would you let a podiatrist take out your gall bladder? No - you listen to those that know what you want to know. Soon, at this rate, you will have nobody left to help you. By the way, I am not responding ... I'm afraid to. Also, don't tell people to read the post again ... that is insulting. People here READ the posts. Your posts have been almost impossible to understand at all. That is not our fault. It is yours.

    No, you can't have pure separation. And yes, you might have to make more changes in the data file if your solution is still young (and occassionally throughout) but that is easily off-set by time saved not migrating. I've designed some large systems using both separation and not. Here are the reasons that *I* prefer using separation and these reasons probably aren't the top reasons at all - but they are important to ME: Transfer of Data (the best solution is NOT moving data) If you use single file and design in another version (so Users can continue working in the served version) you have to migrate the data from the served file to your file and that can take hours even when scripted. Every time you move the data, you risk something going wrong and the likelihood increases each time you migrate. With separation, the data file remains untouched. Import Mapping (unsafe and time consuming) Scripting the automatic export and import on every table in the single file solution takes time as well. Every export and import script must be opened and checked because you have added (and probably deleted) fields. You can make a mistake here. And even if you don’t, the 'spontaneous import map' bug might get you. It is very time-consuming and difficult, dragging a field around in the import maps (FM making it very difficult with the poor import mapping design). No data export/import or mapping with separation. Data Integrity (and User Confidence at risk) When working in a single served solution, you risk records not being created when scripts run (if you are in field options calculation dialog), triggers firing based upon incorrect tab order that you just changed on a layout, and a slew of insidious underground breaks most that you will never see until much later. By then, all you will know is that it broke but not why. You risk jangled nerves and lost faith of your Users who might experience these breaks, data loses, screen flashes and other oddities. A User’s faith in your solution is pure gold and it should not be risked needlessly. External Source Sharing (provide ‘fairly’ clean tables for integration needs) It has been discussed many times … why we have to wade through a hundred table occurrence names (particularly if using separation model anchor-buoy of which I'm not a fan anyway) and also have to view hundreds of calculations (which external sources don’t want). It can be a nightmare. Much better with a data file – where calculations are kept to minimum and the table occurrences are easily identifiable base relationships and easy to exchange with MySQL, Oracle and others. If FM made calculations another layer (separate from data) then FileMaker would go to the top instantly … rapid development front-end and true data back end. But I digress … Crashing (potential increases when Developing in live system) Working in developer mode (scripts with loops, recursive custom functions), means that there is higher likelihood of crashing the solution when designing - admit it. If you crash the solution while in the schema, it is (usually) instant toast but regardless, you SHOULD ALWAYS replace it immediately (run Recover, export the data and import it into a new clean clone). With separation model, you never design live so it is moot. No trashed file means no recover and no migration. You are designing as we all should … on a Development box. Transferring Changes (even if careful) Working in live single file system, a change you think is small might have unseen and unexpected side-effects. That potential danger increases as the complexity of your solution grows. This is why we all should beta test changes before going live. But even if careful and even if you design on Developer copy and test it, document your changes and then re-create those changes into the served file (eliminating the data migration portion completely), you risk mistyping a field name, script variable, not setting a checkbox and so forth. Separation also can risk error because it can mean adding a field or calculation to the Data file but it is very small percentage of the changes we make (except very early); most changes are layout objects, triggers, conditional formatting…UI changes. It is more difficult to replicate layout work between files. And most changes in the data file occur before the solution is even made live the first time. Same Developer experience (Developer works in single file regardless) In separation, all layouts and scripts reside in the UI no matter how many Data files are linked as data sources. The only time you have to even open the Data file is to work in Manage Database. Added ... or set permissions. Fewer Calculations (means faster solution?) If one decides to go with Separation, the goal is no calculations or table occurrences in the data file but that goal is not obtainable. Since this is your goal, you try to find alternate methods to achieve the same thing to avoid adding calculations (which you should do anyway). You will use more conditional formatting, Let() to declare merge variables, rearranging script logic to handle some of it … there are many creative options. And once you start down that path, you will find that you need fewer calculations than you ever imagined. Separation model means I can work safely on the UI aside and quickly replace it while leaving the data intact with the least risk. Some calcs need a nudge to update and privileges must be established in the data file as well – those are the only drawbacks I have experienced with it. I have never placed the UI on local stations. I have heard (from trusted sources) that it increases speed. There was a good discussion on separation model here: https://fmdev.filema...age/65167#65167 Everyone has their opinion. I did not want to go with separation and I was forced into it the first time (by a top Developer working with me, LOL). I am glad I was. Once I understood its simplicity and that everything happens in the UI, I was hooked. Of course if it is a very small solution for one person then I won't separate but for a growing business with data being served, I will certainly use it. Next time that, in your single-file solution, you go through a series of crashes because of network (hardware) problems and you have to migrate every night, think about separation. Next time you need to work in field definitions but can't because Users are in the system, think about separation. Most businesses are constantly changing and that means almost constantly making improvements to a solution. You can NOT guarantee that changes in Manage Database or scripts will not affect Users in the system. Risk is simply not in my dictionary when it comes to data. Enough can go wrong even when we take all precautions. I don't dance with the devil nor do I run with scissors. Joseph, I think it would be easier to start from scratch because it makes you re-think each piece. And, as you learn, you will find better ways of re-creating each portion of it. I would also wait until the next version arrives to take full advantage of its new features. It won't be long now.

    Security Vulnerabilities of FileMaker Platform API’s: An Update January 9th 2017 In an April 2016 entry on this BLOG titled The FileMaker Platform API’s Are Your Friends, Right? [http://fmforums.com/blogs/entry/1535-the-filemaker-platform-api’s-are-your-friends-right/] I discussed a number of FileMaker Platform security issues centered on the uncontrolled use of a number of external Application Program Interfaces (API’s). There are at least nine of these API, possibly more, if ExecuteSQL is included. The central thesis of that article was that these API’s provide unexpected attack vectors to compromise FileMaker Platform files. As noted at the time: Many FileMaker developers are not aware, however, that these API’s have the capability to access customer or client solutions in unexpected ways and to extract or insert data, to manipulate business processes developers embedded into these solutions, and to compromise the integrity of these solutions. Unfortunately, in the intervening nine-month time span, we continue to see cases where several of these API have been used for malicious purposes to compromise FileMaker Platform files’ business process integrity, to manipulate data, and to extract data. And many in the developer community remain unaware of this problem. In this BLOG entry, I will describe two of these API’s in greater specificity and detail, including describing a variety of attacks they can facilitate. This article will not discuss the ActiveX API that is available on Windows OS; however, developers should give similar attention to that approach. Developers need to be aware of these items in order to protect their files and those of their clients. The two API at the center of this focus are Apple Events and the FMPURL process. In the earlier article, I noted several elements about these that bear repeating here: [These API] cause particular concern because of their breadth and relative ease of use…. The Apple Events Suite has an extensive set of commands that can read and write data, read metadata, manipulate the UI, and trigger scripts. In addition, they can work outside the normal constraints found on layouts in a file. [http://thefmkb.com/5671] The FMPURL…can open a file and run a script in it. If the file is already open, then the script will still run. [http://thefmkb.com/5560] A few general comments about both of these API’s: · They are not platform-specific in the sense that just because a client organization is an all Windows OS environment that it is immune from an Apple Event attack. It’s the OS of the attacker that controls whether the API can be used. · There are some ways within Privilege Sets to constrain behavior of these API commands when they are applied on a file. The Export privilege bit can control the ability of Apple Events to extract data from a file. The Layout Access privilege bits can also constrain the ability to see contents of a layout. Likewise, Script Access privilege bits can control the availability of a script to either of these API. · These API often perform actions in unexpected fashions that fall outside the normal, traditional, and familiar FileMaker Pro User Interface behavior. This is part of what catches developers by surprise. —Apple Events— When a file is open, whether standalone or hosted by FileMaker Server, an attacker can send Apple Event commands to it causing it to perform a variety of actions, including: · Run any script to which the user has access, irrespective of whether that script is in the list of Scripts or whether it is attached to some UI element, such as a button. · Navigate to any Layout irrespective of whether that Layout’s name is in the list of Layouts or not. If the user’s Privilege Set has access to see that Layout, then its contents are visible whether the developer ever intended for the user to view the Layout or not. · Return various metadata about the file, including such items as Script Names, Value List Items, Layout Names, Field Names, etc. If a user’s Privilege Set does not allow access to the item, its name does not appear in the list returned. · Put data into any field in the database or extract data from any field, irrespective of whether that field is on the active Layout or is on any Layout for that matter. Here are several examples of these scripts, all working on a file named Our_Secret_Information.fmp12. tell application "FileMaker Pro Advanced" activate go to first layout end tell tell application "FileMaker Pro Advanced" activate do script FileMaker script "Relog_as_Admin" end tell tell application "FileMaker Pro Advanced" activate set somevar to name of every layout end tell tell application "FileMaker Pro Advanced" activate set somevar to name of every field end tell tell application "FileMaker Pro Advanced" activate set somevar to get data field "CreditCardNumber" end tell —FMPURL— The FMPURL command’s principal attack vector is that it can be used to run any Script in a file to which a user’s privileges has access. Similar to Apple Events, this occurs irrespective of whether that script is in the list of Scripts or whether it is attached to some UI element, such as a button. If the file is closed, the command first opens the file with supplied credentials, then runs any OnFirstWindowOpen script, and then runs the designated script from the FMPURL command. As a result of this behavior, a Halt Script step at the end of the opening script has the effect of blocking the running of the FMPURL designated script. Some developers have utilized this technique to block FMPURL calls to scripts in a file. However, if the file is already opened or if there is no opening script, then the designated script does run. Here is an example of calling a script, again in our file Our_Secret_Information.fmp12 being hosted at a server at IP address fmp:// Relog_as_Admin —What Is the Significance Of This and How Do We Address This?— One of the many reasons we caution developers against embedding security elements such as Identity and Access Management controls into the data layer of FileMaker Pro databases is precisely because such elements are vulnerable to these API attacks. Think for a minute about that Relog_as_Admin script that presumably relogs into the file with a [Full Access] Account. If an Attacker can trigger that script and cause it to run, irrespective of what the developer might have intended, then the Attacker has full access to the file. This has actually happened. Or, suppose that a developer has made a “Developer_Only” layout in the file, removed it from the list of layouts, and left sensitive information on it. If the Attacker can navigate to that layout, and if it is not protected by settings in the Privilege Set, then the Attacker can learn the contents of the information on it. This has actually happened in numerous instances, including unbelievably, the appearance of [Full Access] level credentials left exposed on the layout! Likewise, suppose that a developer has made a so-called “Privileges Table” with various fields that purport to control whether a user can do such things as create records. Using the Apple Event Set Data command, an Attacker could likely change the values in these fields if they do not enjoy additional protection. More likely even, the Attacker could simply issue a Make New Record command and create the record. That is a process frequently used to thwart developer-imposed limitations on the number of records in a demonstration version of a vertical market solution. So, what can be done to manage this situation and to prevent these type attacks? In FileMaker® Pro 15, FileMaker, Inc. added a new Extended Privilege option in the Privilege Set called fmscriptdisabled. Developers must explicitly invoke this option; it is not a default option. What it does is to prevent Apple Events (Macintosh OS) and ActiveX commands (Windows OS) from activating scripts, just as the name implies. It has no impact on FMPURL or on other Apple Event commands that do not involve triggering of scripts. Some of the other items in a Privilege Set, notably Export and data layer modification elements, can control Get Data and Set Data Apple Events. If Export is disabled, then Get Data will not return data from the selected field. In tables where the editing privileges are restricted, likewise, Set Data will not add data to a field. Creation and deletion privileges behave in similar fashion. Remember, we are talking here only about Apple Events. Other processes may behave differently. Controlling API behavior is important; however, it is not the only security feature that developers must invoke to assure Confidentiality, Availability, and Integrity of their database systems. So, clearly what we need here is a way to block these API from interacting with FileMaker Pro files. FileMaker, Inc. is aware of these issues and has been working on new ways to address them. In the Product Road Map Webinar presented on November 30th 2016, FileMaker, Inc. noted that the next version of the FileMaker Platform will contain a number of additional security enhancements. I am authorized to say that one of those enhancements will be a new process for more closely and granularly controlling several of these API’s. At such time as there is any new version of the FileMaker Platform, I will have additional comments and analyses of the issues related to these API’s.

    I was running some speed tests with EasySync recently and was surprised to see how long a sync took after I added a few images to the the sample record set that ships with EasySync. It was taking over 5 min. to download those records from FileMaker server which was installed on the same machine as FileMaker Pro. A competitor's product was doing the same sync in under 10 seconds. The interesting part was that all records in the sync took much longer to process, once the images were added. In other words, the fact that I added some images to record #1 made records #2-100 take exponentially longer to process. So, I did some digging and found that the entire payload was being saved to a local script $variable in the Pull Payload script. When the payload included images, that $variable was really large; too large to all fit into FileMakers available memory. This caused the number of page faults to increase by about 600,000 while the records were being processed. My theory was that if I could reduce the amount of data store in memory (variables) at once, then I could reduce the time it takes to process a large payload. It turns out this basic concept worked. The sync which previously took over 5 min. now only took 30 seconds! (and page faults barely increased at all) I've attached a file with these changes that prove my theory. I ended up saving each segment returned from the server to a new record in the EasySync table, then only extracting a single record at a time from the payload, reading from each payload segment as necessary. NOTE: the attached file is a proof of concept ONLY! Please do not use it as-is in a production; it has not been tested and will probably fail in all but the most obvious circumstances. Also, my system crashed once while I was working on this file, so it's been closed improperly at least once. DO NOT USE IT IN PRODUCTION! I think I may start a fork of this project which includes this change; I'll post back here if I do. FM_Surveys_Mobile_v1r3_DSMOD.fmp12

    Emerging Trends in Information Security Affect FileMaker Platform By Steven H. Blackwell March 17th 2016 The recently concluded annual RSA Security Conference showcased a number of important emerging trends in Information Security that likely will affect FileMaker Platform developers and Administrators of FileMaker Platform systems. In this BLOG entry, I will describe some of these and offer some observations about how they might apply to the FileMaker Platform. Multi-Factor Authentication (MFA) will increasingly become a standard requirement for Identity and Access Management (I&AM) in organizations of all sizes. This is especially true for connectivity by mobile devices. And it especially true for data hosted in the Cloud. As we saw recently, efforts to create a “two-factor authentication” system inside of the FileMaker Pro client product did not work out well at all. (http://fmforums.com/blogs/blog/112-eye-on-filemaker/) A true MFA system will require coordinated integration with FileMaker Server, wherever that server resides. The data are still the key asset. Outer perimeter defenses, while important, are secondary to protecting the data from the inside out. The data are the asset we most seek to protect, wherever the data reside. For the most part, they reside inside of the database itself. That’s why finely-grained Privilege Sets, strong I&AM, Encryption At Rest, and Encryption In Transit are all so important for FileMaker Platform deployments. Insiders are the new malware. And now, everyone is an Insider. Whether by inadvertence, by curiosity, by carelessness, or by malicious intent, those persons inside organizations and inside organizational supply chains remain a principal threat vector for compromise of digital assets. Any number of major recent data breaches over the past year or so started in the organizational supply chain apparently. Context-sensitive and content-sensitive conditional authentication of identity assertions will become more and more common. What does this mean? A trusted insider accessing data from inside a corporate LAN may trigger one level of authentication requirement. That same user when attempting access from outside the LAN may trigger multiple steps (factors) of authentication requirements. Moreover, access to more sensitive data may require additional authentication factors. And when the context changes mid-session, additional authentication challenges may need to appear. This again will require close integration with FileMaker Server. The need for cyber-insurance will increase dramatically. To mitigate the liability associated with data breaches, more and more organizations of all sizes are going to need to acquire cyber-insurance. Premiums will continue to rise. Organizations of all types and sizes face liabilities such as damage to brand reputation, civil judgments in suits brought by persons whose data are compromised, business interruptions, and–dare I even say it—cyber-extortion. The underwriting process for this will require a more stringent adherence to a range of Best Practices by those seeking the insurance. Small and medium-sized businesses, a staple of the FileMaker community, are perhaps least well equipped to survive a major breach absent this insurance. Regulatory attention to security breaches will increase at both the Federal and State levels. Additionally there will be concomitant increases in scrutiny about whether organizations have employed “reasonable” security practices. What constitutes such practices is sometimes unclear; however, in any given instance, the list may be extensive. The California Attorney General’s Office recently noted that there were at least twenty specific items that any organization should presume to employ in order to meet the standard of “reasonable” security practices. (These are the Center for Internet Security’s Critical Security Controls. https://www.cisecurity.org/critical-controls.cfm) The Attorney General’s report notes that in 2015 approximately 60% of Californians were victims of a data breach of one sort or the other. And the data involved are often the most sensitive type information, including financial data and health-care records. California is often a leading-edge indicator for regulatory actions, and it is entirely to be expected that other states will follow suit here. (https://oag.ca.gov/breachreport2016) So, where does this leave the FileMaker platform and the FileMaker Developer Community? First, developers and administrators need to be sure they have properly aligned the security requirements of their systems to business requirements. This includes such items as brand reputation, customer/client data privacy, civil liability protection, regulatory compliance (State and Federal and international as applicable), and business continuity. I will be having much more to say about this is coming weeks. Second, developers need to follow Best Practices for security in FileMaker Platform files. This includes granular Privilege Sets, Encryption at Rest, and File Access Protection. Third, FileMaker Server Administrators also need to follow Best Practices for deployment, including appropriate OS for servers, a rigorous backup regimen including the tested ability to restore from backups, and Encryption in Transit. Fourth, business unit managers at FileMaker Platform customers need training in Security Best Practices from the user standpoint. Likewise, they should assure that their employees have a similar awareness. Fifth and finally, but certainly not least, we need to encourage FileMaker, Inc. to continue to improve the security schema of the Platform, most particularly the introduction of Multi-Factor Authentication (MFA) and the introduction of additional controls over the behavior of various external API’s. This includes Apple Events, Active X, Execute SQL, PHP, XML, FMPURL, and PlugIns.

    This post is simply to make others aware of a usage of placeholder text that I haven't seen mentioned before. We have situation where, when opening a popover to create a new record, the new record isn't created until the User enters data. However, there are a few auto-enter fields which are defaults and they do not display. This is confusing to Users since, from their perspective, that data should already be there - they don't fill it in unless they want to change the value.! I always keep a field (global) called PLACEHOLDER. It is set to auto-enter ( replace ) with: If ( not IsEmpty ( Self ) ; "" ) and I use it for displaying calculation results on layouts when merge fields will not work but this usage is a bit different ... The PLACEHOLDER field can help with displaying these default auto-enters. No record has been created yet (and may not be if User cancels) but I have set those field's placeholder text to their auto-enter calculation and I've set the placeholder text style to same font color as their regular text. Now default entries display. BTW, this works nicely since when User enters the field, the value remains until the user starts to type, at which time the placeholder text disappears and the user entry displays.

    Another fun option. If you want to get away from the overhead of the conditional formatting. Thanks to @jbante for posting this one. http://uxmovement.com/forms/why-infield-top-aligned-form-labels-are-quickest-to-scan/ I've been playing around with this idea for just over a week now. Noticing layouts built this way look less busy, but still provides all of the info a user needs to know what data in a field. Something that can be lost if the label is hidden. Google does this a lot in their interface ( hiding interface objects and menus ), to the point where it's not intuitive, and you can't find the magic spot for where the menu is hidden.

    So, I finally took the plunge and upgraded the site to the new forum engine. I am planning to work the weekend to restore site features that are currently disabled.  There may be times when the site goes unresponsive or generates an error.  I already have a few trouble tickets pending with the site developers to provide a remedy.  I wish to thank the Site Advertisers for making this possible, but do please forgive the irony as I don't have all the ad spaces working just yet and I hope to restore them as soon as possible. - Having to crash course some html/php/css logic. Think I'll need another cuppa  I hope to have some site instructions as things have changed a bit.  One thing you may have noticed is that before we had usernames and Display Names the site only allowed one so we elected Display Names as they were already public facing - so you will need to login using your Display Name or your email address, or if already configured Facebook or Twitter (hope to include other oAuth login methods in the future )  I'll post more in this topic when there is something you should know.

    I suggest that every act which could have been optimised but wasn't is poor practice. It is not poor practice because of principle but rather because of: If you let slide optimisation in this area on 2,500 records, the next time you'll be inclined to think letting slide with 3,000 records is fine. It is a slippery slope which breeds sloppiness and drags a good solution down into less than ideal. We can not always predict the environment and venue our solutions will be fired under. It may be fine over LAN but when accessed from an iPad with low-grade provider, the process which only took a blink over LAN now takes 4 seconds and THAT is a LONG time to a User. As for me, if I go to a website which takes more than 6 seconds to load, I move on. Users today will not tolerate slop.

    Your "Maior Grid Spacing" is setted to 1 point. You need to change it to something like 10 or more. Or you need to unchek the box: View >> Grid >> Show Grid

    Charity,   Since the best experience is if the end user has all the data they need local to their iPad and not rely on connectivity you may try to do this:   Create your solution in ONE file with multiple tables one table for your catalog another other table for your customer data entry.    If your catalog only changes every so often that is fine you can push out a new version to the end user to replace their database with all the catalog data.   If they only need to add new customers and not look up historical customers then you can essentially have them email data (export as TAB/CSV/or EXCEL )  from the customer table for you to import in to your own file, every night. (not ideal but its a work around)   Since cost is a concern for you please look at this http://fmeasysync.com, its a free open source framework for syncing your database - it may be a bit overwhelming at first but I am confident that you can get there!   -   Charity every year at the developer conference we (old salts) wonder where the "next generation" of FileMaker Developers are coming from, if you have a passion for this and accept the challenges head on, you most likely will be reciprocating your learnt knowledge and wisdom in short time to other newbies jumping in to the fray.   -   What goes into the External Data Sources - really depends on where the files will ultimately be deployed, if two files are hosted then they would use relative paths: file:MyDatabse.fmp12 if one file is local to a device then it needs the fully qualified URL path with either the PUBLIC IP address, or a domain name, if using a 10.0.x.x or 192.168.x.x this is an internal IP address and wouldn't be accessible out side your environment. fmnet:/ fmnet:/fms.somehostingcompany.com/MyDatabase.fmp12 if you would like to see how can be access when hosted please send me a private message and I could host a sample file for you that you can test with.    Stephen

    I know this is lower priority than some of the other wishes but I can't help but just mention it ... If we go to Manage > Themes, we see a list of themes loaded in this file and it also indicates how many layouts are assigned to that theme. But it would be nice if we knew which layouts were assigned to a theme and even had the ability to ... yeah I know ... probably never ... but to GTRR (so-to-speak) to those layouts or see a list of them at least. Manage > Layouts certainly has room to list its theme along with the table and menu set. If nothing else, this would make life easier for us. When a solution has 150 layouts, it can take quite a bit of time to go through them all to find the few layouts assigned to a theme needlessly. And each theme (even themes unused), load all definitions and take up quite a bit of space. For instance, a recent example - file had 13 themes but on 3 were used. By converting them all to the single theme, I saved 1.7MB right off the top and it took 15 minutes. So a way to quickly jump to layouts according to their theme would be helpful. Or ... am I missing something here? Are there ways of seeing a list of layout names per theme? Thanks everyone for listening and hopefully providing a solution of which I was unaware. Otherwise I'll provide FileMaker feedback about it. Also, there is a Custom Themes forum for FM12 but there isn't one for FM13. It might be nice to remove the 'FM12' portion from the forum title so we can put FM13 questions there as well ... or ... create another forum for Custom Themes in FM13. I prefer the former. Thank you!!

    It's perfectly find, even preferable, to keep your process split out into separate scripts. There are plenty of arguments for this from different sources, but I personally think that the best reason is that human working memory is one of the biggest bottlenecks in our ability to write software. It's dangerous to put more functionality in one script (or calculation, including custom functions) than you can keep track of in your head. If you find yourself writing several comments in your scripts that outline what different sections of the script do to help you navigate the script, consider splitting those sections of the script into separate sub-scripts, using the outline comments for the sub-script names. If your parent scripts start to read less like computer code and more like plain English because you're encapsulating functionality into well-named sub-scripts, you're doing something right. (The sub-scripts don't have to be generalized or reusable for this to be a useful practice. Those are good qualities for scripts, but do the encapsulation first.) I think you'd be better off if the scripts shared information with script parameters and results instead of using global variables, if you can help it. When you set a global variable, you have to understand what all your other scripts will do with it; and when you use the value in a global variable, you have to understand all the other scripts that may have set it. This has the potential to run up against the human working memory bottleneck very fast. With script parameters and results, you only ever have to think about what two scripts do with any given piece of information being shared: the sub-script and its parent script. Global variables can also lead to unintended consequences if the developer is sloppy. If one script doesn't clear a variable after the variable is no longer needed, another script might do the wrong thing based on the value remaining in that global variable. With script parameters, results, and local variables, the domain of possible consequences of a programming mistake are contained to one script. I might call it a meta best practice to use practices that limit the consequences of developer error. Globals are necessary for some things; just avoid globals if there are viable alternative approaches. There is a portability argument for packing more functionality into fewer code units — fewer big scripts might be easier to copy from one solution into another than more small scripts. Big scripts are also easier to copy correctly, since there are fewer dependencies to worry about than with several interdependent smaller scripts that achieve the same functionality. For scripts, this is often easy to solve with organization, such as by putting any interdependent scripts in the same folder with each other. Custom functions don't have folders, though. For custom functions, another argument for putting more in fewer functions is that one complicated single function can be made tail recursive, and therefore can handle more recursive calls than if any helper sub-functions are called. This ValueSort function might be much easier to work with if it called separate helper functions, but I decided that for this particular function, performance is more important.

    Do an ExecuteSQL to do a quick select, if that comes up empty you can skip the real FM find. It's important to understand though that "Set Error Capture On" does not prevent the error from *happening*. The only thing it does is hide the error from the user so that you can handle it silently. If you run the same script in your debugger you will see that FM also reports the error.

    My 2 cents: Wherever you state your payment conditions and other important legal info is not the place to try and be funny. Irony is an interpretation and you can not expect everyone to "get it". Even if they "get it" you do not want to leave wriggle room from someone to take it literally and pay you in worthless currency.

    The trick is to use the fmsadmin command line and that syntax is the same on Windows and Mac. So the only challenge is in calling that fmsadmin command line from your favourite OS scripting language: shell script / AppleScript on OSX and batch file / VBscript / PowerShell on Windows.

    Why not load all their information into one global variable and then you can always parse out that info since you should only ever have one row returned. ExecuteSQL ( "SELECT ID, firstname, lastname, title, date_hire FROM Staff WHERE accountName = ?" ; "¶" ; "" ; Session::accountName ) Then you can use GetValue ( ) to parse out specific information.

    This is kind of janky, but you have to insert in a script step that guarantees no error code thrown (like "Show All Records") and then exit the script using the "Exit Script" step. ie. If Get(lastError) > 0 action for failed find Show All Records Exit Script Else action for successful find End If If you have multiple "Perform Find"s, make sure you add the "If Get(lastError) > 0" right after the Perform Find and then "Show All Records" and "Exit Script" steps after your other script steps but before the "End If" or "Else" script step. This suppresses the error in the schedule section of FMS

    The two main schools of thought for passing multiple script parameters are return-delimited values and name-value pairs — the choice is a matter of taste, whether you prefer array or dictionary data structures. Both approaches have solutions for dealing with delimiters in the data. For return-delimited values, you can use the Quote function to escape return characters, and Evaluate to extract the original value: this standard. As long as you have a function to define a name-value pair in a parameter (# ( name ; value)) and another function to pull specific values back out again (#Get ( parameters ; name )), it works, and all variations should behave the same way. Any other supporting functions are purely for convenience, and probably can be re-implemented for whatever representation syntax you want. So I'd write: Quote ( "parameter 1") & ¶ & Quote ( "parameter 2¶line 2" ) will give you the parameter: "parameter 1" "parameter 2¶line 2" and you can retrieve the parameters: Evaluate ( GetValue ( Get ( ScriptParameter ) ; 2 ) ) with the result: parameter 2 line 2 Every name-value pair approach worth using has it's own approach for escaping delimiters. In my own opinion, XML-style syntax is unnecessarily verbose. My personal preference when working with name-value pairs these days is "FSON" syntax (think "FileMaker-native JSON"), which is where the parameters are formatted according to the variable declaration syntax of a Let function: $parameter1 = "value 1"; $parameter2 = "value 2¶line2"; I only consider name-value pair functions practical when the actual syntax is abstracted away with custom functions. Once you do that, the mechanics of working with the different types should be interchangeable, such as any name-value pair function set that matches # ( "parameter1" ; "value 1" ) & # ( "parameter2" ; "value 2¶line 2" ) and: #Get ( Get ( ScriptParameter ) ; "parameter2" ) I only have 2 requirements for any parameter-passing syntax: 1. It can encode it's own delimiter syntax as data in a parameter, and therefore any text value (already mentioned in this thread), and 2. it can arbitrarily nest parameters, i.e., I can include multiple sub-parameters within a single parameter. The requirements tend to work hand-in-hand with each other. If I can do those two things, I can construct everything else I will ever need within that framework.

    Hi Charity, We all deal with wanting to eliminate the display of buttons, checkboxes, drop-down calendars and such on that last row when Allow Creation is in effect. Instead of having to eliminate the objects individually, you can accomplish it all with conditional formatting AND make it clear to your User that they click the last row to add a new record. Here is how: Create a text box with the words [ Add new record here ... ] Make the background transparent. Color of text does not matter Resize the text box to same size as single portal row Format the text box as follows (using conditional formatting) First entry: Formula = not IsEmpty ( the primary key from the portal table occurrence ). Then below select ‘more formatting’ and set the font size to custom and 500. Second entry: Formula = IsEmpty ( the primary key from the portal table occurrence ). And below set the text to white and the background to black as example. You can set it anything you wish. Select this text box and Arrange > Bring to Front and place it over your top portal row. This one text box hides checkboxes, drop-down calendars, buttons, lines on empty fields, etc only on the empty row and also provides a clean row in which to provide your message. I use it on all Allow Creation portals - just by changing the ID referenced within the conditional format portion.

    Since FM14 came out with the new button bars having the ability to calculate data on the fly on layouts for display purposes has been great - the fact that you can display data without a dedicated calculated field or extra relationships just to display a bit of information. So I am generating a document that prints a portal however the data is not connected to the portal in the traditional parent / child relationship - but rather it's showing related data for the given product kits. This invoice line item record is not "parent" to the portal of kit items. That presented a challenge - originally i had a convoluted way to generated this report using a virtual list but the it required a bit more effort to generate, so how to get totals to display properly in the portal row to multiply quantities - and to also show a total of items packed? One thought would be to put global fields in to the kits lookup table and then set them which would drive keys to the data tables via dedicated relatiohships just prior to generating the report, but that just felt awkward. Here is what I came up with. The row of 6 kits are what the customer ordered based on this there needs to be 108 pieces based on the piece count for each item in the kit multiplied by the quantity ordered. Example 6 x 12 = 72 as you can see by the first row in the portal. To get the value of the 72 I added a singe segment button bar to the portal and multiplied the 6 by the 12 pretty simple. This was all great but I also needed to get a total for the total items packed but that is based on yet another table not directly tied to the kit table. So by adding a second calculation button segment and this formulae I was able to get the necessary data. Hope you find this useful. Cheers.

    I don't see anything "unusual" in this numbering scheme. This question comes up quite often: you have a parent-child relationship, and you want to number the children of each parent with its own series (prepending the other digits representing the parent ID and the year/month is trivial). Usually, the idea is to take the maximum existing value in the series (available either from the point-of-view of the parent, or through a self-join relationship of the child table based on matching parent ID), and add 1 to that. Which will work 99.9% of the time - until two users create records roughly at the same time and end up with duplicate numbers. So the first "challenge" is to prevent such situation - and it could be accomplished by (a) forcing the users to create new child records by script only, and (b) having the script lock the parent record first and, failing to do that, abort the task. However, the "challenge" doesn't end there: you must also consider what will happen if user decides that the parent selected initially is not the right one and needs to be changed to another. Instead of dealing with this, let me also point out that if any record is deleted, you will have a gap in the series anyway. So the real question I would ask here is this: is the goal worth the means required to achieve it?

    [Content moved by OP from "FileMaker 14 Script Workspace" forum] Man alive, how long have FM developers pined for something like this!!! One thing about the Script Workspace is that it continues to reveal its secrets the more you work with it. Here are a few tips that make scripting faster and more fun to boot: 1. How do you insert a Comment line? The obvious way, of course, is to type a hash (aka "number/pound/octothorp") sign (simultaneous right pinky on the Shift key — left middle finger on the 3, or some equivalent thereof on other keyboard layouts), then type your comment. But try this instead: Hit Space, followed by Return, then comment away. (Space drops down a list of all available steps, with # at the top, pre-selected as the default.) If you're at all dexterously challenged, this might be the easier way, and is my favorite discovery so far! 2. It's not just the obvious initialisms that are supported (GTRR, PSOS, etc.), but every single command can be entered by typing its initials: afb gets you "Allow Formatting Bar," sec gets you "Set Error Capture," and so on down the list. 3. You know that you want to insert some sort of window adjustment step, but can't remember which one (Adjust Window? Move/Resize Window? Make Window Go Away?) or the exact name of the command? Type "window" — even just "w" will do — and you'll get the list of script steps with "window" in them as autocomplete suggestions. You don't have to type from that actual start of the desired step for autocomplete to work; it'll work with any word in the command. 4. It's a bit hidden, but you can edit the syntax-highlighting colors if you don't like the defaults. Find it under "View > Syntax Coloring…" when you're in the Script Workspace. That's right, now you can kill hours each day tweaking the colors to your heart's content. It's an OCD dream come true! 5. While we've always been able to run a script directly from the Manage Scripts window — or was it from the Edit Script window? how fast I forget — it's now possible to simultaneously open the script debugger and run a selected script all via a single button in the Script Workspace window. 6. Scripts remain backward and forward compatible with previous versions. Specifically, blank lines added in the FM14 Script Workspace simply become empty comment lines when opened in 13 or earlier. (And while I'm at it, hooray for blanks lines!) But, perhaps even cooler, all those empty comment lines you've previously added to your scripts to space things out are displayed as blank lines when opened in 14! BTW, I see that Martha Zinc has posted a nice intro video on the new Script Workspace among the "Unboxing FileMaker 14" videos over at the Soliant site. Check it out! Got other tips you've discovered? Post 'em here. Mark

    I would say that the idea is to append something to the values that do not end with the specified suffix. This is done in three steps: Protect the values that do end with the specified suffix from being modified in step 2 by substituting the suffix and the subsequent return with a reserved character (a);Substitute all remaining returns with a reserved character (b) and a return; this effectively appends (b) to all values that do not end with the specified suffix;Reverse step 1 .The result of this is indeed what you show in your post: abc@gmail.com def@yahoo.co(b) xyz@gmail.com abcdes@hotmail.com(b) tuv@group.gmail.com and when this is used to filter the original list, only the unmodified, wanted values remain. IIRC, I developed this idea out of something that Agnès Barouh did, I don't recall exactly what that was.

    I did a video with Richard Carlton http://filemakervideos.com/filemaker-14-svg-icon-helper-tool-filemaker-14-training/ about SVG files and created a small helper tool. In that video, I explain why I set the fill color to white, so that the icons appear nicely in the FM icon palette. You can see in the helper tool, how I did it and change to whatever you like, since it is completely free and unlocked.

    You can also style a single segment button bar as a button that does nothing with a calculation for the label, then style it to match a field or text on the layout and use it for layout level calculations with out the need to add a calculation to the schema.

    The proper way to do this is to use Amazon's web API, not scrape the web page. They will change their layout very frequently and that will break your scraping part. Use the developer tools that Amazon has and you will get the data in a standard format.

    Hi Wayne, If you change a CF, any stored calculations which use the CF will not change in response. You will need to change the calculation to unstored in calculation Storage Options (check Do Not store calculation results). Exit back to the layout then go back in and unchecking 'do not store'. It will then adjust. It is considered expected behaviour but it can catch folks off guard as you've discovered. I would suspect that the reason is simply because a stored calculation never re-calculates (unless a FIELD referenced within it changes) It is no different than regular stored field data.

    Fascinating!! Prior to identifying the tools, the questions must be asked ... not the question of whether to analyse our business data in this broad sense but what do we want to achieve from the analysis. For example, many years ago, I migrated 10 years of complete business data from a Wholesaler in to a new FileMaker solution which integrated accounting, inventory, sales - the entire business. As I viewed the data, there appeared to be patterns and spikes in sales and I thought it was because of full moon. I wondered if Buyers contacted our Wholesaler company in patterns. Why would I care? Because if we could predict a pattern of contact, we could predict sufficient sales staffing and even contact those Buyers who didn't call us ... thinking they probably wanted to call us (like all other Buyers) but were too busy. Maybe the sales calls to these chains during low periods were less fruitful ... we could change our methods accordingly. So the questions I asked (and finally COULD ask because we had gathered the data) were: Gender: Is same sex (Buyer to Sales Rep) more productive or the reverse? Who contacts first ... if we call them or wait for them to call us? Time of day, day of week, day of month? ... and my favourite ... do sales spike during a full moon? Back then, there were no databanks on the web of surveys and studies like there is today. Neither did I have college background so I had no Statistics or analytical skills. But even winging it, we DID find patterns and sales increased by 20%. The full moon comparison showed a negligible spike but the biggest percentages were day of month and day of week. :-) I look forward to this discussion because the power of data modelling is underestimated. Thank you for opening this discussion (and to Stephen for opening this forum)! It is a subject which has always intrigued me and I look forward to learning from everyone about tools, calculations or methods to take full advantage of our data.

    Assuming there are at most two night periods to consider (the one that begins on the same day as ClockIn, and either the one before or the one after - depending upon ClockIn occurring before NightEnd or after), try the following (not tested very thoroughly) = Let ( [ nightStart = Time ( 21 ; 0 ; 0 ) ; nightEnd = Time ( 5 ; 0 ; 0 ) ; N0 = Timestamp ( GetAsDate ( ClockIn ) ; nightStart ) ; N1 = Timestamp ( GetAsDate ( ClockIn ) + 1 ; nightEnd ) ; direction = Case ( GetAsTime ( ClockIn ) ≥ nightEnd ; 1 ; -1 ) ; N2 = N0 + 86400 * direction ; N3 = N1 + 86400 * direction ] ; Max ( Min ( N1 ; ClockOut ) - Max ( N0 ; ClockIn ) ; 0 ) + Max ( Min ( N3 ; ClockOut ) - Max ( N2 ; ClockIn ) ; 0 ) ) The result type should be Time. This returns results similar to the ones in your examples, with the exception of #5 where it returns 6:00:00 - which I believe is the correct result.

    One more thought has occurred to me: what would happen if you changed your host's location? Why am I bringing this up? To illustrate that Get (CurrentHostTimestamp) is NOT an attribute of a transaction. A transaction recorded in New York with the timestamp of the server in Sydney becomes "out of sync" with a later transaction recorded in New York with the timestamp of the server in Los Angeles. In order to get everything back on the same timeline, you would need to adjust the old transactions' recorded timestamps - and that's a clear sign of poor structure. Recording both the local timestamp and the location should provide all there is to know about when a transaction took place. And if you also record the UTC, you won't have to figure out when a particular location switched to or from daylight saving time.

    One of the features that are in FMP13 is a new option for a summary field that will gather the records into a list ( List Of ). Though it isn't exactly a calculation or function that we were looking for, it is great that we finally get something that has been needed for a while. I haven't tried benchmarking it against copy all though.

    FileMaker Server will try to execute the SQL query on the server so you will only get the result. If that result is a record set of thousands of records then obviously that is what FMS will have to send you. There is one exception to FMS doing the query for you: if you have an open record in your session for the target table then FMS will send you the whole table so that your client can perform the query including the results of your open record. That is usually not a problem unless there are more than say 10,000 records in the target table. And the wait becomes exponentially longer the more records in the target table. An example: Table with 1,000,000 records. You construct a SQL query that results in 1 record. You have no open records in the target table (if other people have open records, that does not matter) --> FMS will do the query and return you the data for the one record. And it will be fast Table with 1,000,000 records. You construct a SQL query that results in 1 record. You DO have open records in the target table (if other people have open records, that does not matter) --> FMS will send you the data for ALL 1,000,000 records and your local copy of FMS will execute the SQL query. It will be very slow.

    360Works plugins talk to a licensing server when they are first launched to validate the license key, and to ensure that the product is not exceeding the maximum number of licensed users.   In addition, when the plugin is shut down, it sends a signal to the license server asking it to decrement the count of connected users.   However, if that's all we did, then any unexpected shutdown would leave an orphan record showing a connected user, which would cause the count of connected users to be incorrectly higher than it should be. That's why we send a heartbeat signal every 30 seconds - if the license server does not receive this signal on a regular basis, it knows that FileMaker exited unexpectedly, and it decrements the user count.   Here is the data payload that we receive when the plugin connects. There is no personal data in here. This particular example is for ScriptMaster:   Section 1: <LicenseCheck><RegisteredTo>[changed]</RegisteredTo><LicenseKey>[changed]</LicenseKey><ProductCode>48</ProductCode><MajorVersion>1</MajorVersion><MajorReleaseDate>1279166400000</MajorReleaseDate><VersionString>4.201</VersionString><ExtraInfo></ExtraInfo><FmEnvironment><Platform>Windows 2003</Platform><JavaVersion>1.7.0_21-b11</JavaVersion><Architecture>x86</Architecture><Language>en</Language><Country>US</Country><ApiVersion>52</ApiVersion><AppType>3</AppType></FmEnvironment></LicenseCheck> Section 2: <ApplicationVersion>ProAdvanced 11.0v2</ApplicationVersion><HostApplicationVersion>Server 10.0v2</HostApplicationVersion><HostIPAddress>[changed]</HostIPAddress><MultiUserState>2</MultiUserState><SystemIPAddress>[changed]</SystemIPAddress><SystemNICAddress>[changed]</SystemNICAddress><SystemPlatform>1</SystemPlatform><UserCount>0</UserCount>   We carefully engineered this to use minimal resources. The heartbeat signal is sent out by a background thread that only wakes up once every 30 seconds and uses just a few milliseconds of CPU time before going back to sleep. Since it's on a separate thread, it will not block the main thread from running, even if it is unable to communicate with the server for some reason. It also uses an extended HTTP keepalive socket so that it's not having to re-connect to the server for every request.

    The Location and LocationValues functions both report an accuracy for the returned location in meters, but I can't find any documentation reporting what measure of accuracy is being returned. Is it CEP? CEP95? 2DRMS? None of FileMaker's documentation says, and neither does Apple's documentation on the CLLocation class.

    The challenge comes when on 1 January the year rolls over and the serial number resets to 1, several projects are created AND THEN somebody wants to create a project and back-date it to the previous year. It can be done if you are smart and use a table to store the project numbers: each record is a year, with a field to store the next project number. As projects are created the serial number is incremented. When a new year is started, a new Year record is created and the serial numbers for this year are tracked. The previous year's serial numbers are still remembered. If somebody wants to create a project for last year, just look up that year's record and increment that serial number.

    I am using ExecuteSQL() to gather values and display them as merge variable on buttons. If we attach a button to them, they re-evaluate just by hovering over them (please see attached file). This is new file created for this purpose and I have replicated it in other files as well. The top right grey buttons switch to the correct value as you make changes to the checkbox but then when you hover, the merge variables revert to the prior value. I've solved it (potentially) by using a separate transparent button over them. If the button is separate, the value will not revert. It is only when the button itself has a script attached and you hover on it that the value reverts (only once). I cannot figure out how to make it NOT revert except with separate button. To me, the hover and conditional formatting merge variable should NOT be interacting. Now this may not be the best process. But this is the best example of what I am experiencing. Change a value in the checkbox and you will see the number 1 properly change. Then hover over the number '1' again and it will revert and STAY reverted until you refresh again. Very annoying. The thing is ... you will see I am desperately trying to force a refresh but that isn't the issue. It DOES REFRESH quite fine. But when hovered, it re-evaluates using the old value.

    One must be careful when using SQL in a solution with a mind for testing for performance. SQL can be excruciatingly slow over the WAN. In those cases, I have found that FileMaker relationships can be much faster. http://www.mightydata.com/blog/results-vs-techniques-filemaker-sql-wan-performance-troubles/ Darren Burgess

    Jeremy's file is meant to be set as your desktop background and displayed at actual size NOT shrunk/stretched to fit. You can do better than that - create a new FileMaker file with a script that captures information about the available window space, then have your boss email that file back to you (or have it email you the data directly). Have a look at these functions, for some ideas of the types of data you can capture: Get(WindowContentHeight) Get(WindowDesktopHeight) Get(WindowHeight) Get(ScreenHeight) On Windows, some of these values can change based on the size of the Application window, or if the database window is maximized.

    You're doing fine with variables. As you've already figured out, lookups can only refer to one related source table each. If you need data for a given field to come from different sources in different situations, lookups are not for you. I can't remember the last time I used a lookup, and I've known some developers who advocate never using them as a matter of principle. Using variables in a scripted record creation process makes it easier to see what data is moving from where to where, in my experience. It can be confusing to maintain solutions where some data movement is defined in the schema (Manage Database...) and some is defined in scripts. The counterargument for managing all the data movement with variables in a script is that if you make a different script for creating the same records, you may wind up duplicating some of the business logic for what data comes from where that could be maintained in one place in the schema. If you find yourself doing that, I still recommend keeping the $variable based workflow. You can make one script that handles all the business logic the two operations have in common, and another for what's different about each operation. You can call the general- and special-purpose scripts in succession (I prefer this option), or make the general script a sub-script of the special-purpose scripts. Two other ways for moving data between tables on record creation are auto-enter calculations and between-table imports. Auto-enter calculations would let you put the logic in the schema, plus the flexibility to reference different related tables in different situations for the same field that you don't get with lookups. Imports can be faster that transferring data with $variables, though it can make for a slightly more difficult-to-maintain script, depending on the complexity of your data flows, and it doesn't accomodate transforming data during movement as well as auto-enter calculations or $variables.

    Personally, I use three custom functions to assist with creating SQL statements. They would allow me to write the statement like this... ExecuteSQL ( "SELECT " & SQLField( Courses::__ID ) & " FROM " & & SQLTable( Courses::__ID ) & " WHERE " & SQLField( Courses::_CourseName ) & "=" & SQLQuote( "Git Training" ) ) Here are the custom functions: /* SQLField ( name ) PURPOSE: Return only the name of the field, without the relationship portion. As opposed to GetFieldName() which also returns the relationship. This is to be used in SQL queries to protect the field references from breaking if the field is renamed. The Quote() function allows us to reference "SQL reserved" field names without having to manually escape them.

    For those that have field names that start with and underscore such as some do when identifying key fields, the new ExecuteSQL function does not play nice with them directly. Normal escapes with a prime or quotes do not work. You must use the Quote function. ExecuteSQL ( "SELECT " & Quote ( "_kp_ID" ) & " FROM table"; "," ; ¶ )
