Kevin/Dave: Thanks for your feedback. Changing the driver to Access with Unicode returned the same error, although running the query outsdie CF is successful. Kevin: I removed the "0 = 0" portion as it is no longer needed. Thanks for pointing that out. The error reamins, however. Could you describe the SQL I can use to perform the query another way? Dave: I agree that the database structure should be modified. Unfortunatley, I inherited the design and the DB is being used by another application. Changing the architecture would have a definite impact in other areas. I will look into the possibility of using Verity. Thanks to both of you for your replies. -Mike ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Logware (www.logware.us): a new and convenient web-based time tracking application.
