ROLLBACK(7) PostgreSQL 15.7 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 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.
