PolarDB:COMMIT

Last Updated:Jun 12, 2024

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.

Synopsis

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

Parameters

  • 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;
