ABORT — abort the current transaction
Synopsis
ABORT [ WORK | TRANSACTION ] [ AND [ NO ] CHAIN ]
Description
ABORT
rolls back the current transaction and causes all the updates made by the transaction to be discarded. This command is identical in behavior to the standard SQL command ROLLBACK
, and is present only for historical reasons.
Parameters

AND CHAIN
If
AND CHAIN
is specified, a new transaction is immediately started with the same transaction characteristics (seeSET TRANSACTION
) as the just finished one. Otherwise, no new transaction is started.
Notes
Use COMMIT
to successfully terminate a transaction.
Issuing ABORT
outside of a transaction block emits a warning and otherwise has no effect.
