Hi,
 
you can make use of ISNULL function of SQL. which will replace the DBNull value with your custom text or value (based on the datatype).
--Example.
SELECT ISNULL(ColumnName, 'Your Text') AS 'Value' FROM TabelName
you can refer ISNULL[^] for more information.
 
hope it helps

Try this one
 
  SELECT p.ProductId,
                     p.ProductName,
                     CASE 
                          WHEN p.[Description] IS NULL THEN '-'
                          ELSE p.[Description]
                     END AS 'Description'
              FROM   Products p
