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.
