Yes, that is nice way to work with databases, but I am on PHP4 and I
am not using the PDO.
But getting back to my problem - perhaps there is something I
misunderstood: is it the client application responsibility to check if
the transaction failed or succeeded and issue COMMIT or ROLLBACK
accordingly (how do I close the transaction block in that case)?
Or is it the database server that is suppose to check if transaction
succeded and perform the query, or ROLLBACK if anything went wrong?
