Hi.

I need to make a trigger which fires when after an UPDATE is done on
table A in database X. The trigger must perform a statement which
copies some of the data from the update to table B in database Y on
the same server.
My question is: Can I access the data which caused the trigger to fire
or just get an indication of which entry in table A had been updated?

Best Regards
Jens Christian Andersen.

There are 2 pseudo-tables available in trigger code: "deleted" and
"inserted". When a trigger is fired by an UPDATE statement, the "deleted"
table contains images of the rows before the update and the "inserted" table
contain the row images after the update. In your update trigger code, you
can do something like:

INSERT INTO Y.dbo.B (Column1, Column2)
SELECT Column1, Column2
FROM inserted

In a trigger fired by a DELETE statement, the "deleted" table contains the
rows just deleted and the "inserted" table is empty. Similarly, when a
trigger is fired by an INSERT statement, the "inserted" table contains the
rows just inserted and the "deleted" table in empty. See the Books Online
for details.
