NAME

       ROLLBACK - abort the current transaction

SYNOPSIS

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

DESCRIPTION

       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.

       AND CHAIN
           If AND CHAIN is specified, a new (not aborted) transaction is immediately started with the same
           transaction characteristics (see SET TRANSACTION (SET_TRANSACTION(7))) as the just finished one.
           Otherwise, no new transaction is started.

NOTES

       Use COMMIT to successfully terminate a transaction.

       Issuing ROLLBACK outside of a transaction block emits a warning and otherwise has no effect.  ROLLBACK
       AND CHAIN outside of a transaction block is an error.

EXAMPLES

       To abort all changes:

           ROLLBACK;

COMPATIBILITY

       The command ROLLBACK conforms to the SQL standard. The form ROLLBACK TRANSACTION is a PostgreSQL
       extension.
