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.
