ExecuteSQL() list

Trying to wrap my head around ExecuteSQL().  I haven't used it enough to be fluent in it yet.


I have a calculation in the Classes table to count the number of boats in a region:

"SELECT count ("OwnerID")
FROM "Class Member Data"
"Region" = ? 
and  "ClassID" = ?
and "ownerCurrent" = ?";
"";""; 1; ID; 1; 1

(ID is a field in the Classes table.)  


Which gives me a number, but not the same number as performing a Find for Region = 1 and ClassID = Classes::ID and ownerCurrent = 1 in a Class  Member Data layout.


So I want to create a list of OwnerIDs to see where the discrepancy lies to allow me to figure out the reason for it.


I created another calculation field

FROM "Class Member Data"
"Region" = ? 
and  "ClassID" = ?
and "ownerCurrent" = ?";
"";""; 1; ID; 1; 1

which only returns one OwnerID, where I was expecting a list of all OwnerIDs that fit the WHERE criteria.


What have I overlooked or misunderstood?

Are the region, ClassID and ownerCurrent fields numbers or text?

Why 4 optional variables when you are using 3?

What happens if you hard code the query into the select first?

      Having trouble with an ExecuteSQL calculation. I used SeedCode's SQL Explorer to build the calculation. It works fine if I use literal values from a specific record; but if I instead change it to a field reference, the calculation fails. I get the message <unrelated table> in the Data Viewer. The code is below. Am I misusing the field names somehow?   // Build SQL Query q = "SELECT SUM ( " & ainterestMineralDecimal & " ) FROM " & a@LINEITEMS & " WHERE " & a_id_lease & " = ? AND " & a_id_tract & " = ? AND " & a_id_unit & " = ? " ;   // Run SQL Query result = ExecuteSQL ( q ; Char ( 9 ) ; "|*|" ; @LineItems::_id_lease ; @LineItems::_id_tract ; @LineItems::_id_unit ) ] ;   Thanks,   Tom RuBane

      I have used the combination of ExecuteSQL and ValueCount quite a few times throughout my databases before, with almost no issues. Generally what I will do is set a variable by running an ExecuteSQL, then take a ValueCount of that variable. Then with that ValueCount I will loop through my original ExecuteSQL variable.
      However, I am now trying to do something different with this combination. Instead of using the ValueCount variable for a loop, I'm trying to use it as a Global Variable that will be displayed on the main menu. Here is an example of the code I'm trying to use:
      Set Variable [$source; Value: ExecuteSQL ( "SELECT UUID FROM Inspections WHERE Inspector = ? AND Accepted ≠ Accepted" ; "" ; "" ; $$fullName )] Set Variable [$$accepted; Value: ValueCount ( $source )] The UUID field is, as expected, an auto-entered "Get ( UUID )" field. The Inspection table is a table containing all of our part inspections. Each inspection begins with it's Accepted field having a value of "Rejected", if the correct parameters are met this field will become "Accepted". The Inspector field contains the first and last name of whomever conducted the part inspection. The $$fullName variable is set previously in this same script by comparing the user's Username to a Table that contains all of our user's Usernames and Full Names.
      What I was hoping to do is use a Merge Variable on our main menu that displays our $$accepted variable, showing the user how many unaccepted inspections from that particular user in our database.
      However, it only ever displays a value of "1". One of our users has 6 unaccepted inspections in our database currently, but this script only shows that he has 1.
      I am wondering if you can't use Merge Variables or ExecuteSQL in this way, or if I'm simply missing something obvious.
      Please let me know of any more information I should provide. Thank you for any assistance you may offer!

      I have created a "viewer" using a virtual list technique and ExecuteSQL.  The "viewer" is a portal that contains one field - a unstored calc text field from the virtual list table.
      This allows me to run a script for a "report" and have the results appear in this field. I can run a different script and have different data appear in that field.  Everything works great, except column widths.
      I understand how to adjust Tabs, alignment, etc using FM>>Line Spacing>>Tabs.  However, that sticks to the field regardless of the data it is showing.
      I can use hard tabs in the script to place tabs where I want but only for FM fields or text (for column headers for example).  I set a dozen tabs in FM>>Line Spacing>>Tabs - one every 50 points and then used Hard Tabs n the script to move column headers (simple text) over as many tabs as desired. This works great.
      However, I can't figure out how to control the column width WITHIN the ExecuteSQL function.  I need this, as I will end up with dozens of "reports" that I want to view in this single field, all created on the fly via scripting.
      Is it possible to control the tab width with the ExecuteSQL function or am I heading down the wrong path?
      Thanks in advance for any suggestions!

      This is my first time posting, and I apologize if this is the wrong place. I've only been filemakering for a few months, so again, apologies if this is a stupid problem.
      I could use some advice.   I'm working on a solution that must create monthly reports in the following form:   http://i.imgur.com/Cf4Fjic.png   I've given up trying to bend the summary fields to my will, and began using the following approach:   Make two new tables - Queries and Reports.   In queries table, I have fields for M1, M2, M3, Region, Category, Subcategory and four result fields (M1, M2, M3 and YTD.) I also have foreign key into the reports table.   Then in reports table, I portal into the Queries table.   When report is run, a bunch of queries in queries table are created. The Results are populated via ExecuteSQL expressions.   My question is mainly this: Is this too backwards? I feel like maybe this is too weird of an approach and I"m just missing something simple about reporting and creating summaries?

      I am dealing with a very weird condition in my solution where an ExecuteSQL statement was failing to return a matching record. 
      My solution tracks documents such as deeds and leases, where a document can have N grantors and N grantees. So I have a Parties table, a Documents table, and identical join tables, Grantors and Grantees. 
      I noticed the problem when printing out a report, and a particular document didn't have any grantees. The report uses the executeSQL query in question. So I looked for that document in the database, and the particular grantee appeared as expected in the portal. I looked in the Grantee join table, and there was a matching record, complete with the ID of the Party and the ID of the document. I then checked, and every record where that particular party appeared, in the report that party was omitted for every record where it should have appeared. In one record, that party was 1 of 6 grantees. The ExecuteSQL statement returned the other 5 parties, but not that particular one.
      In the course of troubleshooting, I created a new record for that party, nameFirst = Mollie, nameLast = Sternberg. Then I added the new Mollie Sternberg record to those documents. The original Mollie Sternberg record, I set the formerly empty field nameMaiden to "Bugged". Then I re-ran the report. The new Mollie Sternberg record appeared as expected, but so did the original record, Mollie Sternberg Bugged. So I don't know why changing a field in the party table for that record would cause the ExecuteSQL statement to return it, when it hadn't been returning before. 
      I'm freaked out, because I identified a second party that was having the same issue. Changing that party's original record to nameMaiden = Bugged also caused it start showing up, too. But I don't know how many other Party records may be having the same problem, and I have no way to identify a characteristic of the Party record that may have caused the probelm, so that I can identify potential problem Party records. 
      Is this a bug in FileMaker? Or an issue with my SQL query? Any thoughts or suggestions most appreciated. The query is below.
