rollback(7)
NAME
ROLLBACK - abort 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 [commit(7)] to successfully terminate a transaction.
Issuing ROLLBACK when not inside a transaction does no harm, but it
will provoke a warning message.
EXAMPLES
To abort all changes:
ROLLBACK;
COMPATIBILITY
The SQL standard only specifies the two forms ROLLBACK and ROLLBACK
WORK. Otherwise, this command is fully conforming.
