COMMIT

COMMIT — commit the current transaction

Synopsis

COMMIT [ AUTONOMOUS ] [ WORK | TRANSACTION ] [ AND [ NO ] CHAIN ]

Description

COMMIT commits the current transaction. All changes made by the transaction become visible to others and are guaranteed to be durable if a crash occurs.

Parameters

AUTONOMOUS

Optional key word that can be used when committing an autonomous transaction. For details on autonomous transactions, see Chapter 16.

WORK
TRANSACTION

Optional key words. They have no effect.

AND CHAIN

If AND CHAIN is specified, a new transaction is immediately started with the same transaction characteristics (see SET TRANSACTION) as the just finished one. Otherwise, no new transaction is started.

Notes

Use ROLLBACK to abort a transaction.

Issuing COMMIT when not inside a transaction does no harm, but it will provoke a warning message. COMMIT AND CHAIN when not inside a transaction is an error.

Examples

To commit the current transaction and make all changes permanent:

COMMIT;

Compatibility

The command COMMIT conforms to the SQL standard. The form COMMIT TRANSACTION is a Postgres Pro extension.
