FilterValues, part 2

Sometimes it happens that the real value of a blog posting emerges in the comments section. Such was the case last time, when Paul Jansen posted an elegant little workaround to remedy a performance issue with the FilterValues function. Paul’s workaround is deserving of its own demo, and that’s what we’re going to look at… Continue reading FilterValues, part 2 View the full article

FilterValues

Today we’re going to do some experiments with the FilterValues function, which takes two return delimited lists for input… FilterValues ( textToFilter ; filterValues ) …and produces the intersection of the two lists as output. With the above in mind, when the function was first introduced back in 2004, I assumed that these two statements… Continue reading FilterValues View the full article

Ordering Elements within JSON Objects

Introduction If you’ve generated JSON objects via FileMaker, you’re likely aware of the disparity between the order in which you specify the elements, and the order in which they subsequently appear (i.e., alphabetized by key name). As I wrote two years ago (in Thinking About JSON, Part 2)… Both JSONSetElement and JSONFormatElements will automatically alphabetize… Continue reading Ordering Elements within JSON Objects View the full article

GetFieldName Revisited

Long time readers of this blog will be familiar with the following scenario — An ExecuteSQL code example is given, e.g., ExecuteSQL ( " SELECT SUM ( net_amount ) FROM cc_transactions WHERE batch_date = ? AND batch_region = ? AND card_type = ? " ; "" ; "" ; $theDate ; $theRegion ; $theCard )… Continue reading GetFieldName Revisited View the full article

Virtual Portal, part 2

Demo file: virtual-portal-v2.zip (requires FM 18 or later) This is a quick follow up to the Virtual Portal article I posted the other day. As you may recall, the objective was to use virtual list to display disparate entities in a portal… …via an array like this… …which was auto-generated via a Hide Object calculation… Continue reading Virtual Portal, part 2 View the full article

Virtual Portal, part 2

[Note: several hours after posting this article I realized the “Hide Object” calc could be streamlined. Screen shot and demo have been updated to reflect this.] Demo file: virtual-portal-v2b.zip (requires FM 18 or later) This is a quick follow up to the Virtual Portal article I posted the other day. As you may recall, the… Continue reading Virtual Portal, part 2 View the full article

Virtual List Simplified

Demo file: virtual-list-simplified.zip Note 1: The example in today’s article and demo file is intentionally very basic. Note 2: The demo is self-populating to keep the data current, so the values you see in the screen shots will not exactly match those you encounter in the demo. Recently I had the pleasure of discussing virtual… Continue reading Virtual List Simplified View the full article

While some… Continue reading Table Of Contents for FileMaker Hacks View the full article

Fixed in 18: List + GetNthRecord Bug

Recently I was working in FM 17 and ran into an unexpected bug. My use case was more complex than this, but the following bare bones demo illustrates the problem. Demo file: List+GetNthRecordBug.zip Given two tables joined via a standard primary-key-to-foreign-key equijoin relationship… This works as expected. You might think you could get rid of… Continue reading Fixed in 18: List + GetNthRecord Bug View the full article

New in FM 18: While, part 2

Today we’re going to dig a little deeper into the new-in-18 While function, and to avoid repetition, will assume readers are familiar with last month’s article on SetRecursion and While. We’ll examine some new examples ranging from basic to advanced, talk about the circumstances under which While can use variables previously declared via Let, and […] View the full article

New in FM 18: SetRecursion and While

Author’s note: Inevitable comparisons will be drawn between the new While function and the venerable CustomList custom function, which I wrote about at length several years ago. Preliminary testing indicates that CustomList is faster under certain circumstances and While is faster under others. In my opinion, both of them belong in your developer tool kit.
