I am using SQL Server 2000 and would like to create an update trigger that
populates another table with some of the values of the columns of the
current table. How would I go about this?

thanks

Brian

CREATE TRIGGER trgInsertCustomer ON CUSTOMERS
FOR INSERT
AS

insert into ACTIVITY_TABLE
select * from INSERTED

This assumes the existence of a table called ACTIVITY_TABLE. For this
example to work, ACTIVITY_TABLE has to have a structure that is identical to
CUSTOMERS.

The INSERTED table represents all rows currently being inserted (i.e. the
new rows) into the table for which the trigger was created. It only exists
in memory, and within the context of an update or insert trigger.

If you want, you can use only certain values from the INSERTED table, add
some of your own (getdate(), username, etc.) and insert that into
ACTIVITY_TABLE. ACTIVITY_TABLE would then have a different structure.
