ABORT
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
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) 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.
Examples
To abort all changes:
ABORT;
Compatibility
This command is a QHB extension present for historical reasons.
ROLLBACK is the equivalent standard SQL command.
