RELEASE SAVEPOINTNameRELEASE SAVEPOINT -- destroy a previously defined savepoint SynopsisRELEASE [ SAVEPOINT ] savepoint_name Description 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, see ROLLBACK TO SAVEPOINT.) Destroying a savepoint when
it is no longer needed may allow 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.
Parameters- savepoint_name
The name of the savepoint to destroy.
Notes Specifying a savepoint name that was not previously defined is 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.
Examples To establish and later destroy a savepoint:
BEGIN;
INSERT INTO table VALUES (3);
SAVEPOINT my_savepoint;
INSERT INTO table VALUES (4);
RELEASE SAVEPOINT my_savepoint;
COMMIT;
The above transaction will insert both 3 and 4.
Compatibility This command conforms to the SQL:2003 standard. The standard
specifies that the key word SAVEPOINT is
mandatory, but EnterpriseDB allows it to
be omitted.
