Thanks. This is what I'm trying to do now... do you know how I can
refer to the row that has just been added or modified?

In Table1 I have...

CREATE TRIGGER (tr_updateMaster) ON dbo.Table2
FOR INSERT, UPDATE
AS
Here I would like to put something like...
Insert into Table2 new row + 2 extra columns (status and date)
AND/OR
Update modified row in dbo.Table2 with different values in Table1


Thanks again :-)
