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.
