ingres_rollback — Roll back a transaction

ingres_rollback ( resource $link ) : bool

ingres_rollback() rolls back the currently open transaction, actually cancelling all changes made to the database during the transaction.

This closes the transaction. A new transaction can be opened by sending a query with ingres_query().

Возвращает true в случае успешного завершения или false в случае возникновения ошибки.
