ROLLBACK(7)              PostgreSQL 16.2 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 (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.
