TRIGGER FOR UPDATE (reply)
Hi, Harish
old values are stored in the table deleted, so code in your update trigger would look :
CREATE TRIGGER tri_t1_update ON dbo.t1
FOR update
AS
Begin
INSERT T2 (stamp, name, status) SELECT stamp, name, 'UPDATED' FROM deleted
end

I HAVE TWO TABLES IN THE DATABSE T1 AND THE SECOND TABLE(T2) IS FOR AUDITING.
THE STRUCTURE OF BOTH THE TABLES IS SIMILAR WITH ONE MORE COLUMN 'STATUS' IN THE T2.
I HAVE ALREADY WRITTEN THE TRIGGERS FOR THE INSERT AND DELETE TRIGGERS SO THAT I CAN SAVE THE
RECORD WITH STATUS OF 'NEW INSERT' OR 'DELETE' OR 'UPDATE' IN THE AUDIT TABLE(T2).
HELP ME IN WRITING THE TRIGGER FOR UPDATE.
MY PROBLEM IS I DON'T KNOW HOW TO STORE THE UPDATED COLUMNS VALUES INTO VARIABLES AND SO THAT
I CAN STORE THE OLD VALUES INTO THE AUDIT TABLE(T2).
I M USING SQL SERVER 6.5, SO WE CAN NOT USE COLUMNS_UPDATED() IN THE TRIGGER.
PLEASE SUGGEST ME THE CODE SO THAT I CAN STORE THE OLD ROW IN THE TABLE(T1) TO TABLE (T2)
WITH STATUS 'UPDATE' IN THE T2.
PLEASE SUGGEST ME..ITS URGENT.
THANKS IN ADVANCE
