Need your help

Hi,
I need your help on something. I have to write a
trigger (in sybase) that does this: Everytime a record
gets updated it should update a column in that record
with the current date/time. I am able to do it for the
whole table, but how do I make sure the update happens
only for that record which is being updated? Please
respond.
Thanks a bunch,
Jyotsna.
