ROLLBACK(7) PostgreSQL 13.3 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.
