How can I do a BEFORE UPDATED trigger with sql server?

Question

I\'m using Sqlserver express and I can\'t do before updated trigger. There\'s a other way to do that?

Answer 1

The updated or deleted values are stored in DELETED. we can get it by the below method in trigger

Full example,

CREATE TRIGGER PRODUCT_UPDATE ON PRODUCTS
FOR UPDATE 
AS
BEGIN
DECLARE @PRODUCT_NAME_OLD VARCHAR(100)
DECLARE @PRODUCT_NAME_NEW VARCHAR(100)

SELECT @PRODUCT_NAME_OLD = product_name from DELETED
SELECT @PRODUCT_NAME_NEW = product_name from INSERTED

END
