<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>
