Oops, I messed up the 0.4.8 data as I was
cutting and pasting.
Corrected, actual data sent by 0.4.8:
Query: set implicit_transactions on
RPC Name: sp_datatype_info
Query: INSERT INTO sa_test (data, time) VALUES ('bingo',
'2009-03-24 15:08:12')
Query: IF @@TRANCOUNT > 0 COMMIT TRAN
Query: SELECT COUNT(*) FROM sa_test WHERE data='bingo'
Query: IF @@TRANCOUNT > 0 ROLLBACK TRAN
So, no BEGIN TRANSACTION (or SET
IMPLICIT_TRANSACTIONS OFF).
