Hi Fabio,
Just curious

Wouldnt this
SQLEXEC(,'BEGIN TRAN;write command;COMMIT')>0
be same as
SQLEXEC(,'Insert ...')>0 since it executes in only one batch ?

COuld U explain a bit ?

If you can complete the transaction with a single batch
( if the "write command" not required other feedback data from the client's application )
then do it with a single batch.

The
SQLEXEC(,'BEGIN TRAN;write command;COMMIT')>0
is like
SQLEXEC(,'BEGIN TRAN')>0 AND SQLEXEC(,'write command')>0 AND SQLEXEC(,'COMMIT')>0
but it is faster and the probability that it go ok is upper.

If "write command" is a single T-SQL, then BEGIN TRAN;;COMMIT are implicit.

Fabio
