Actually, you have nested transactions in FB, sort of :-) Work done by
stored procedures or triggers is unwinded on error or user exception, so
if you want to use a "nested transaction" just in procedure or trigger
(not at app. level), you can throw and exception for rollback and use
WHEN command to define subtransaction blocks.
