Trigger Blocks
A trigger block consists of a single statement, or zero or more statements starting with DO and ending with END, that defines a database trigger, user-interface trigger, or procedure trigger. It appears as part of a user-interface widget or trigger definition, and can contain all other types of blocks except procedure blocks. A trigger block executes in response to an event, depending on the type of trigger. For more information on database triggers, see Database Triggers." For more information on user-interface triggers, see Widgets and Handles." For information on procedure triggers, see the "External Procedures" section in this chapter.
