How Is Represented The Updated Table In A Trigger?

Hello

I am a newbie creating triggers and I would like to know what is the name of the updated logical table. That is, since the are identifiers like "inserted" and "deleted" that represent the inserted and deleted rows, respectivaly, I presumed that "updated" existed - but it does not.

I have a table with a column named "UpdatedTimeStamp" which I would like to update anytime the other columns are modified. I intended to create the following trigger:

create trigger myTrigger
on myTable
after update
as

update updated set UpdateTimeStamp=GetDate()

Of course, "updated" is not a valid identifier that represents the updated row.

Please, help me in creating this trigger. What is the correct way of doing a trigger like this?

Thanks a lot in advanced.
