I had a table like this

id int identitty(1,1)
productname varchar(20)
Status char(1) like this

IF(@ACTION='U')
BEGIN
IF EXISTS(SELECT P_ID FROM TBL_PRODUCTS WHERE P_ID=@P_ID) 
BEGIN
 set @exp=(select COUNT(*) from TBL_PRODUCTS where P_NAME=@P_NAME)
 set @exp1=(select count(*) from tbl_products where p_id=@P_ID and p_name=@P_NAME)
 if((@exp<=1)and (@exp1=1))
   Begin
UPDATE TBL_PRODUCTS SET
P_NAME=@P_NAME,
P_TAG_LINE=@P_TAG_LINE,
P_WEB=@P_WEB,
P_ACTIVE=@P_ACTIVE
WHERE P_ID=@P_ID;

IF(@@ERROR=0)
BEGIN
SET @ERROR_ID=1
