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

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
