SQL - Language Statements

COMMIT

commit the current transaction

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
==========

chained transactions

`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
    [???](#sql-set-transaction)) as the just finished one. Otherwise, no
    new transaction is started.

Notes
=====

Use [???](#sql-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.
