I have been trying to find info on the web about the differences between these statements, and it seems to me they are identical but I can't find confirmation of that or any kind of comparison between the two.
What is the difference between doing this:
BEGIN
-- Some update, insert, set statements
END
and doing this
BEGIN TRANS
-- Some update, insert, set statements
COMMIT TRANS
?
Note that there is only the need to rollback in the case of some exception or timeout or other general failure, there would not be a conditional reason to rollback.
