Mark,
Anything inside your begin/end transaction will be rolled back to its status before the transaction began if you use the 'Rollback' command. Obviously you will have to trap for any trigger failures. A common scenario is to store the return value of each tableupdate() and do a rollback if any update fails.

>I have a table file that lists valid users. In the update trigger, I have hand-coded RI. It does a cascade update to the 4 tables that contain user code. I am wrapping this in a transaction. What actually happens on tableupdate? I am concerned the trigger updates will encounter locked records. What happens to the transaction if the trigger fails?
