<div><p>For an external trigger, the program containing the set of trigger
actions can be defined in any supported high level language that creates a
*PGM object.</p>
<p>The trigger program can have SQL embedded in it. To define an external
trigger, you must create a trigger program and add it to a table using the
ADDPFTRG CL command or you can add it using iSeries™ Navigator. To add a trigger to
a table, you must:</p>
<ul><li>Identify the table</li>
<li>Identify the kind of operation</li>
<li>Identify the program that performs the actions that you want.</li>
</ul>

The change operation can be an SQL INSERT, UPDATE, or DELETE statement, or an insert, update, or delete high-level language statement in an application program.
