trusty (7) ROLLBACK.7.gz

Provided by: postgres-xc-client_1.1-2ubuntu2_amd64 bug

NAME
       ROLLBACK - abort the current transaction


SYNOPSIS
       ROLLBACK [ WORK | TRANSACTION ]


DESCRIPTION
           Note
           The following description applies both to Postgres-XC and PostgreSQL if not described explicitly.

       ROLLBACK rolls back the current transaction and causes all the updates made by the transaction to be
       discarded.


PARAMETERS
       WORK, TRANSACTION
           Optional key words. They have no effect.


NOTES
       Use COMMIT(7) to successfully terminate a transaction.

       Issuing ROLLBACK when not inside a transaction does no harm, but it will provoke a warning message.


EXAMPLES
       To abort all changes:

           ROLLBACK;


COMPATIBILITY
       The SQL standard only specifies the two forms ROLLBACK and ROLLBACK WORK. Otherwise, this command is
       fully conforming.
