I am writing an update trigger that I want to fire when any field changes.  It 
looks like two ROWS can be compared very easily, but not the two RECORDS OLD 
and NEW.

Is there a way to do:

NEW IS DISTINCT FROM OLD

in a trigger?

This would help me not have to write a specific trigger for each table.

Thanks,

Craig
