IF OBJECT_ID('Sales.uspGetSalesYTD', 'P') IS NOT NULL
    DROP PROCEDURE Sales.uspGetSalesYTD;
GO
CREATE PROCEDURE Sales.uspGetSalesYTD
@SalesPerson nvarchar(50) = NULL  -- NULL default value
AS 
    SET NOCOUNT ON; 

-- Validate the @SalesPerson parameter.
IF @SalesPerson IS NULL
BEGIN
   PRINT 'ERROR: You must specify the last name of the sales person.'
   RETURN

-- Get the sales for the specified sales person and 
-- assign it to the output parameter.
SELECT SalesYTD
