Обсуждение: trigger examples

I need to write a trigger to create a new record in log table if it's a
new record or if column A and B changes. Can someone give me an example
how to do this.

Are there any sites that gives trigger examples??

Thanks.

The example uses C. Is it possible to create the trigger with plpsql
function?

This is an example script I use to keep a log of all database operations on
my tables.
Hope it helps.
