Changing a SUM returned NULL to zero

Question

I have a stored procedure as follows:

CREATE PROC [dbo].[Incidents]
(@SiteName varchar(200))
AS
SELECT
(  
    SELECT SUM(i.Logged)  
    FROM tbl_Sites s  
             


        

Answer 1

You'll have to use ISNULL like this -

ISNULL(SUM(c.Logged), 0)      

Or, as Michael said, you can use a Left Outer Join.
