BUG #: 352492 (SHILOH_BUGS)
When you execute a SELECT COUNT(*) statement to retrieve the count of all records in a table against a linked DB2 server on a mainframe that is using it's four-part name, the following error message occurs:
Server: Msg 7321, Level 16, State 2, Line 1 An error occurred while preparing a query for execution against OLE DB provider 'DB2OLEDB'. [OLE/DB provider returned message: A SQL error has occurred.
