ROLLBACK(7)                       PostgreSQL 12.3 Documentation                       ROLLBACK(7)



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 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(7) 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.
