The short answer was that while inside a transaction I was re-assigning a recordset object variable to point to a newly instantiated recordset object without first closing the recordset object that previously pointed to. ADO didn't like this, so it purposely passed an invalid SQL statement to the server so that the server would be forced a rollback of the entire transaction. The statement: "SELECT INVALID SELECT STATEMENT TO FORCE ODBC DRIVER TO UNPREPARED STATE;" is what ADO passed to the server to force an exception. Although I have only experienced this project with reassigning opened recordset object references, I would expect and reassigning other opened ADODB object would produce the same result. -- Regards, Richard Broersma Jr. Visit the Los Angles PostgreSQL Users Group (LAPUG) http://pugs.postgresql.org/lapug
