Syntax

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

Syntax diagrams

Read left to right. Branches are choices, bypasses are optional, loops repeat. Select an underlined parameter to open its rule.

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

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 PostgreSQL extension.
