On Update (trigger hint) - Mailing list pgsql-general

Hi guys,

Please, give me some advices on how to do the
following:

I have the following table:

CREATE TABLE products (
   id            SERIAL,
   description   TEXT,
   lastupdate    date
);

Well, I would like to update the column "lastupdate"
with the value "now()" on every UPDATE executed on a
row of this table.

Do I have to create a function to do it? Can you help
me?

Regards,

Marcelo
