RE: Log file of file changes

Why use a trigger when you can journal the table? The journal has job info, creation date, job identifier, program making the change and even remote IP address in addition to having the entire row's contents.

Subject: Log file of file changes

All,

We had an issue recently about how a couple of prices got changed. The salesrep (who has _some_ control over pricing) says he didn't do it, and no one in the office remembers doing it. In fact, it was the sales rep who brought it up wanting to know what the %#@* is going on? :) By looking at month end backups, I know it happened sometime in August. Nothing like bringing it to our attention on a timely basis, right?

Anyway, in discussing it, the buying VP suggested a log file of changes. I think it's a great idea and it seems to me to be an ideal use for a trigger. Whenever a record is added/updated/deleted, just have the trigger write the record to this log file. It can have the same record layout as the file in question, plus add a few fields such as user and timestamp.
Seem reasonable? I've never written a trigger before but I can figure it out.

The file is currently journaled, but that's not really what journaling is for, IMO.

Thanks for any ideas.
