From my research, the trigger would be called for every read…even those which are strictly programatic. So, if a program reads through every record in the file to do something, or if you run a query against the file, or an SQL statement…I believe you’d get a record written to your log file for each.

Of course, I’m sure that you could read some info into the trigger program (or a program that the trigger submits for batch processing) that could determine if the read access was from an ‘allowed’ source, such as a certain program and just not inundate your log file with unwanted records.

YMMV. This is purely from memory, and it was a couple of years ago when I dug into this. I did learn some helpful things about triggers and how they can be written to minimize their effect on your database speed. But…that’s a topic for another question… ;)
