Answer : how do i update primary key

why you are trying to updated that column which is used for filter the record and you are also updating with the same value.

Please look below modified code...


ALTER       PROCEDURE SPR_UPDATE_PRODUCTS
      (
       @prodID         int,
       @prodCode       varchar(10),
      @prodName       varchar(30),
      @prodDesc       varchar(200),
      @pfID           int,
      @prodLicName    varchar(50),
      @prodLicEncKey  varchar(20),
      @supported      smallint,
      @licVersion     smallint,
      @prodAltCode    varchar(10)
     )
AS
UPDATE product SET
      prodCode     =@prodCode,
      prodName     =@prodName,      
      prodDesc     =@prodDesc,      
      pfID         =@pfID,          
      prodLicName   =@prodLicName,    
      prodLicEncKey =@prodLicEncKey,
      supported     =@supported,    
      licVersion    =@licVersion,    
      prodAltCode   =@prodAltCode  
WHERE
       prodID = @prodID
