Hi John,

The problem is that macro substitution is not supported on SQL. Am I right here?

What you could have on the SQL Server end is an sp_ where it opens the record and does the SELECT statement from that setup table using a variable to represent the entire text and then passes the cursor back when called from SQLEXEC in VFP. I don't see why that wouldn't work.

Then I could create a view on the front end, add a record with the full string desired and commit the record to the back end... Then with that ID assigned, I could call a stored procedure on the back-end and select the value from the text into a variable and execute from there? Is this possible?
