Oracle PL/SQL - PL SQL Function Procedure Package Triggers

Introduction

A trigger is a procedure stored in the database and implicitly fired, when something happens.

Different events may fire a trigger.

These events are always divided into three groups:

• DML triggers,
• INSTEAD OF triggers, and
• system event triggers.
