A trigger is similar to a stored procedure in many respects. Like a stored procedure, a trigger is an object that is defined in a data dictionary. However, unlike stored procedures, triggers are not executed by client applications. Instead, they are executed by Advantage in response to row-level data operations.

In this chapter, you will learn how to create and register triggers. We begin with a look at the types of triggers that are supported by Advantage. Next, you will find trigger examples written in SQL, Delphi, C#, and VB for .NET. Finally, you will learn how to register and configure triggers.

 
NOTE: If you are unfamiliar with SQL, you may also want to refer to Chapters 10 through 14 while reading this chapter.
