Scope the trigger execution

Scope the trigger execution

Is it possible to have a trigger program that executes only on changes to specified fields in a file? If not, does IBM plan such support in DB2/400 in the future?
Yes, SQL triggers introduced in V5R1 allow you to scope the trigger execution to a specific field or set of fields. SQL Triggers can be defined over both SQL tables & physical files.

IBM currently does not have any plans to add this support for external triggers (i.e., ADDPFTRG command).
