The DirectConnect access service supports the following three MDI Database Gateway™ transformation modes for backward compatibility:
tsql0 – works in the same way as passthrough mode and will be phased out eventually.
tsql1 – provided for backward compatibility only and also will be phased out. It works as it does in the MDI Database Gateway for DB2, version 2.05.
tsql2 – provided for backward compatibility only. It works the same way as sybase mode.
