Use a separate query and check the values of it with the old values of the
columns to be posted.
I think it is easier to use a trigger to increment a "generation" ID on a
record. That way if a user changes something and you have the generation ID
as a part of the key, IBO can detect the change and refuse them the ability
to post the record.

But it is useful only for Insert operation not for Update (modify / edit),
isn't it?
