COMMIT PREPARED

commit a transaction that was earlier prepared for two-phase commit

COMMIT PREPARED

transaction\_id

Description
===========

`COMMIT PREPARED` commits a transaction that is in prepared state.

Parameters
==========

transaction\_id

:   The transaction identifier of the transaction that is to be
    committed.

Notes
=====

To commit a prepared transaction, you must be either the same user that
executed the transaction originally, or a superuser. But you do not have
to be in the same session that executed the transaction.

This command cannot be executed inside a transaction block. The prepared
transaction is committed immediately.

All currently available prepared transactions are listed in the
[pg\_prepared\_xacts](#view-pg-prepared-xacts) system view.

Examples {#sql-commit-prepared-examples}
========

Commit the transaction identified by the transaction identifier
`foobar`:

    COMMIT PREPARED 'foobar';

Compatibility
=============

`COMMIT PREPARED` is a PostgreSQL extension. It is intended for use by
external transaction management systems, some of which are covered by
standards (such as X/Open XA), but the SQL side of those systems is not
standardized.
