I want to be able to make my data methods be able to access tables in either MS SQL Server or VFP databases. I've set up an MS SQL data source and a VFP data source. The tables in each are basically identical in design taking in consideration the differences of MS SQL and VFP. Without having to maintain two separate versions of my data engine I'd like to be able to access either set of tables depending on the circumstances. For development and demos I'd probably set it up to run against VFP data. For live production systems I want to run it against MS SQL Server.

My problem is this: When accessing the MS SQL server I can include code at the bottom of the SQL UPDATE command to check the @@ROWCOUNT property and if it is zero I can raise an error to report it back to the VFP method which takes appropriate action. That works. However, when accessing a VFP table via SQL Pass Through there is no way I can find to detect if the command affected any rows in the table. The _TALLY system variable is not affected by ODBC commands.

So,my question is: Is there a way to detect if a SQL UPDATE command did or did not affect data in any rows?
