OLE DB Provider Change

The OLE DB provider now requires that you specify the database name as part of a four-part identifier.

The OLE DB provider requires this syntax for identifers:
SELECT * FROM LS153.iqdemo.DBA.emp1
The OLE DB provider supported by versions of Sybase IQ prior to 15.3 required this syntax:
SELECT * FROM LS152..DBA.emp1

Apply a recent EBF to update earlier versions of Sybase IQ with a more recent version of the provider.
