ROLLBACK v6.27.4
This section is adapted from the WarehousePG v6.x documentation
Stops the current transaction.
Synopsis
ROLLBACK [WORK | TRANSACTION]
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.
Notes
Use COMMIT to successfully end the current transaction.
Issuing ROLLBACK when not inside a transaction does no harm, but it will provoke a warning message.
Examples
To discard all changes made in the current transaction:
ROLLBACK;
Compatibility
The SQL standard only specifies the two forms ROLLBACK and ROLLBACK WORK. Otherwise, this command is fully conforming.
