RELEASE SAVEPOINT

Function

RELEASE SAVEPOINT destroys a savepoint previously defined in the current transaction.

Destroying a savepoint makes it unavailable as a rollback point, but it has no other user visible behavior. It does not undo the effects of commands executed after the savepoint was established. To do that, use ROLLBACK TO SAVEPOINT. Destroying a savepoint when it is no longer needed allows the system to reclaim some resources earlier than transaction end.

RELEASE SAVEPOINT also destroys all savepoints that were established after the named savepoint was established.

Precautions

• Specifying a savepoint name that was not previously defined causes an error.
• It is not possible to release a savepoint when the transaction is in an aborted state.
• If multiple savepoints have the same name, only the one that was most recently defined is released.
