I'm getting that done today thru a large static trigger script and I
would like something more dynamic...
For that it is needful to look up the table
to change from one invocation
of the trigger to the next, so don't have the dynamic code inside the

Hi,
Just quick reading your email, forgive me if I'm mistaken
what about serializing using *concat(old.f1,'|||',old.f2,'|||',old.f3)
('|||' = any separator that works for you)*
and deserialize inside the function?
does this make any sense to you?

I could do that, but I was hoping I wouldn't have to specify the
individual fields, and just pass the collection for parsing.
If I were to add any fields I would have to re-write the trigger which
is something I was trying to avoid.

The way to create triggers is:

The trigger I want is only on UPDATE.

FOR EACH ROW
