Error trying to modify SQL in Data Provider

I am attempting to modify the generated SQL in a DESKI 3.1 report and save with the Do Not Generate box checked.

If I attempt to modify the generated SQL and check the Do Not Generate box when I click on OK or Verify SQL button I get the following error:

Exception: DBD, [Microsoft][ODBC SQL Server Driver][SQL Server]Statement(s) could not be prepared.State: 42000

Any ideas as to what could be the problem?

Thanks.
