NAME

       ABORT - abort the current transaction

SYNOPSIS

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

DESCRIPTION

       ABORT rolls back the current transaction and causes all the updates made by the
       transaction to be discarded. This command is identical in behavior to the standard SQL
       command ROLLBACK, and is present only for historical reasons.

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 COMMIT to successfully terminate a transaction.

       Issuing ABORT outside of a transaction block emits a warning and otherwise has no effect.

EXAMPLES

       To abort all changes:

           ABORT;

COMPATIBILITY

       This command is a PostgreSQL extension present for historical reasons.  ROLLBACK is the
       equivalent standard SQL command.
