I believe we determined that our behavior was very very close to complient, but that it does not match the standard reading of that section. My reading of the spec came out as: The spec in regard to exact behaviour at COMMIT in the presence of errors is, in spec language, undefined. The current PostgresQL behaviour doesn't violate the spec, but is also one of many possible mutually contradictory behaviours (such as not rolling back on error) that don't appear to violate the spec. Ahh well, its not like inserting explicit ROLLBACKs is that hard. -- J C Lawrence -(*)Satan, oscillate my metallic sonatas.

I suspect serial types also exhibit similar behavior to sequences. Ahh, that's actually critical information (which makes sense too BTW). thinks Excellent. Then as long as the auto-ROLLBACK on error is a guaranteed ANSI behaviour rather than a PGSQL thing, everything is just perfect. Thanks. -- J C Lawrence -(*)Satan, oscillate my metallic sonatas.

Re: [GENERAL] COMMIT after an ERROR?
The failed query will abort the transaction, and throw out every command that comes before or after it until your rollback. You don't have to specifically issue a rollback unless you want to issue more commands though. When you disconnect from the DB it will automatically roll back the transaction.

J C Lawrence [EMAIL PROTECTED] writes: Does an error during a transaction invalidate the transaction? Yes, the transaction goes into ABORTED state and nothing after the error will succeed. Translation: Do I need to monitor for error conditions during a transaction and manually do the ROLLBACK in those cases?
