I want to do statement level triggers for performance, but it seems 
there is no 'updated', 'inserted', or 'deleted' tables inside the 
trigger and nothing I can find in the documentation that offers similar 
functionality.

Is there any way that I can access only those rows that were changed?

Thanks
Ralph
