How to know only updated columns in a trigger?

414300Mar 17 2004 — edited Mar 18 2004
Hi,
In a trigger i want to know all the updated columns. I can compare :new.value and :old.value but my table has got around 60 coulmns.

Is there any way to find what the columns updated(only updated) when user executes a UPDATE Query.

Thanks in advance.
