COMMIT

COMMIT — commit the current transaction

Synopsis

COMMIT [ 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

WORKTRANSACTION: 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 PostgreSQL extension.
