Solution 1

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).

SQL

--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
