I'm pretty sure that the Sql statement below (as mentioned above) caused the problem since it fired an error when it was run from the application.  My concern is did this do any damage to the database? Should there be any corrective action taken or?  The database seems to be running fine at this time.  Any help would be greatly appreciated.
