ROLLBACK
Stops 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) as the just finished one. Otherwise, no new transaction is started.
Notes
Use COMMIT to successfully end the current transaction.
Issuing ROLLBACK when not inside a transaction block emits a warning and otherwise has no effect. ROLLBACK AND CHAIN outside of a transaction block is an error.
Examples
To discard all changes made in the current transaction:
ROLLBACK;
Compatibility
The command ROLLBACK conforms to the SQL standard. The form ROLLBACK TRANSACTION is a Apache Cloudberry extension.
