>If you will be able to provide example that works within ODBC guidelines and demonstrates the fact that backend violates the assumption "SQLSETPROP(con,"Transactions",2) is a logical equivalent of BEGIN TRANSACTION" i.e.: doesn't combine transaction sensitive commands into single transaction, doesn't perform appropriate locking and logging, fails to commit/rollback changes, I will be the first agree with you. :-)

This is clearly not going anywhere and serves no useful purpose. I do understand what you are saying but your understanding of the meaning of 'equivalent' and mine are obviously different.
