String variables were concantenated together. What is IIRC? In the example I gave, there were no line continuations. String variables were concantenated together. What is IIRC?

Then switch it to the SQL text. That text is copied to the inside of a formula like this: Function SQLdemo(var1 as String.....,) as string SQL text goes here. End Function Then I make 4 or 5 variables named line1, line2... line5 (one for each line of the SQL statement) So it looks like this: Function SQLdemo(tablenamehere as String.....,) as string Dim line1, line2, line3, line4, line5 as String line1 = "INSERT INTO......" line2 = "SELECT ...." line3 = "FROM " & tablenamehere & " INNER JOIN....." line4 = "WHERE...." 'etc. as needed. SQLdemo = line1 & line2 & line3 & line4 & .... End Function Then I go through the text and place the variables. Above just demonstrates the variable tablenamehere being the name of a table. When done I have a formula which will output a valid SQL statement and I have control of what values I will feed it in the code that does the work. Most of these SQL creation functions will add to a collector database table. When finished, the table has all the answers needed. I pull out the answer I need using Excel and other formulas (using Application.vlookup). Anyway, that's how I do it. Since most of my SQL statements are to be manipulated by code I first make an Access query in query designer. Then switch it to the SQL text. That text is copied to the inside of a formula like this:
Function SQLdemo(var1 as String…..,) as string
SQL text goes here.

End Function

Then I make 4 or 5 variables named line1, line2… line5 (one for each line of the SQL statement)

So it looks like this:
Function SQLdemo(tablenamehere as String…..,) as string
Dim line1, line2, line3, line4, line5 as String
line1 = “INSERT INTO……”
line2 = “SELECT ….”
line3 = “FROM ” & tablenamehere & ” INNER JOIN…..”
line4 = “WHERE….”
‘etc. as needed.
SQLdemo = line1 & line2 & line3 & line4 & ….
End Function

Anyway, that’s how I do it.
