Hi,
I'm trying to make some sort of function, rule, trigger, or what ever that=
=20
would be capable of modifing my table on an update.

Basically, I have 5 fields, one being a PK (SERIAL), 3 with information, an=
d=20
the last one a timestamp field that will show the last time the register wa=
s=20
modified (tmodif which has a DEFAULT CURRENT_TIMESTAMP).

Now, eveytime someone modifys any, or all of the 3 information fields, I wa=
nt=20
the tmodif field of that register to be set to now(). I tried with rules, b=
ut=20
just didn't work (obviously, and not so), even with INSTEAD.

The only way I see of doing it is through a view/rule, but I would leave th=
at=20
as the last resource.

Any ideas?
