Chapter 8. Using DB2 Triggers for Integrity

IN THIS CHAPTER

• What Is a Trigger?

• Trigger Guidelines

Triggers can be created on DB2 tables to extend the functionality of DB2 databases. By creating triggers, you can create active databases that take action based on naturally occurring database activities. Most of the other major relational database management systems have provided trigger support for a number of years . DB2 was late to the game with triggers (introducing them in V6), but IBM's offering is a very rich, functional implementation of triggers.

If you have not had the opportunity to use triggers, their power may elude you at first. However, once you have used them, living without triggers can be unthinkable.
