Question

I’m working in sql server 2005 here and I wanted to know if there was a way to make a stored procedure take variable a or variable b for its parameters.

Right now if I declare A and B it requires both A and B. Possible to make it take A or B instead? So that if the other one doesn’t have a value it uses the other?

ex:

@ID VARCHAR(255)
@MAKE VARCHAR(255)  
AS  
BEGIN  
    SET NOCOUNT ON  
    SELECT *  
    FROM CARS   
    WHERE ID = @ID OR MAKE =@MAKE

Thanks!

Answer 1

create procedure MyProcedure
(
    @ID VARCHAR(255) = NULL,
    @MAKE VARCHAR(255) = NULL
)  
AS  

    SET NOCOUNT ON  

    SELECT *  
    FROM CARS   
    WHERE 
        (@ID IS NOT NULL AND ID = @ID)
        OR 
        (@MAKE IS NOT NULL AND MAKE =@MAKE)
