A database trigger is a stored subprogram associated with a database table, view, or event. You can create, browse, edit, compile, download, drop, disable or enable a trigger and view report.
The trigger can be called once, for example when an event occurs, or many times, for example for each row affected by an INSERT, UPDATE, or DELETE statement.
