RELEASE SAVEPOINT savepoint_name

Keywords

savepoint_name

Represents a named savepoint (or target specification) created earlier in the transaction with the SAVEPOINT statement. The savepoint_name must be unique within the transaction.

Rules at a Glance

Use the RELEASE SAVEPOINT statement within a transaction to destroy a named savepoint. Any savepoints that were created after the named savepoint will also be destroyed.

To illustrate the behavior of savepoints, the following example code inserts a few records, creates a savepoint named first_savepoint, and then releases it:

INSERT authors (au_id, au_lname, au_fname, contract )
VALUES ('111-11-1111', 'Rabbit', 'Jessica', 1);
SAVEPOINT first_savepoint;
INSERT authors (au_id, au_lname, au_fname, contract )
VALUES ('277-27-2777', 'Fudd', 'E.P.', 1);
INSERT authors (au_id, au_lname, au_fname, contract )
VALUES ('366-36-3636', 'Duck', 'P.J.', 1);
RELEASE SAVEPOINT first_savepoint;
COMMIT;

In this example, the first_savepoint savepoint is destroyed and then all three records are inserted into the authors table.

In the next example, we perform the same action but with more savepoints:

INSERT authors (au_id, au_lname, au_fname, contract ...
