Re: Trigger programme without a trigger.

Here is an actual scenario:
I work for a paging company. We have a few applications that allow user
to add/remove/change "Carbon Copy to email address" feature on any
pager. When this feature is added to a pager, all messages sent to this
pager will get "Carbon Copy" to the email address specified. Everything
works fine.

6 months later, business unit requests IT to modify system to start
sending a message to the pager when a "Carbon Copy To Emaill Address"
feature is added/removed/update on the pager. The catch all solution
for this request is to add a trigger to the "Carbon Copy To" file. When
a record is added/updated/changed, this new trigger program will fires
an email to the pager to notify customer about the change. Some of
those applications that maintains the "Carbon Copy To" file
updates/adds/changes this file under commitment control. How should you
write this trigger to make sure that trigger only fires the email after
the changes is committed?

You can't ... which is why it's an incorrect use of a trigger.
