Yeah, we need to test that under (windows-only) Microsoft's sqlsrv driver.
In any case, Rajesh, something is still bad/missing in your "mssql" installation. You should not get failures in test_reset_sequence() nor test_change_field_type() nor test_concurent_transactions().
Note that does not affect result of testing. I'm passing here the "mssql" ones properly, with the expected (3 exceptions + 4 failures). But the extra 3 failures you're getting are not expected at all.
Waiting for Michael results using "sqlsrv"...
