Here I think Transactions should be defined since mssql support > them. This array is used by the user to determine if the feature is available. This can either mean this is a natively supported feature or it is emulated. However the driver test suite expects all tests to succeed, because the goal of MDB is to allow database independent development. Regards, Lukas
