I have the following stored procedure that works fine. I would like to tidy up one thing - the 'Jan' column displays data and null values, I would like to replace the null values with 0. Can anyone tell me how to do this (I am using SQL Server 2005)?

ALTER PROCEDURE [dbo].[RollingAFR]
(
@Year INT
) AS
BEGIN
SELECT O.Region, O.Description, (SELECT (Sum([VSeverity].[CountOfSeverity])*100000)/Sum([VHours].[Total]) AS AFR
FROM [VHours] LEFT JOIN VSeverity ON ([VHours].Unit_Office = VSeverity.Unit_Office) AND ([VHours].Year = VSeverity.Year) AND ([VHours].Period = VSeverity.Period)
WHERE ((([VHours].Unit_Office)= O.Description) AND (([VHours].Year)=@Year) AND (([VHours].Period)<=1)) OR ((([VHours].Unit_Office)= O.Description) AND (([VHours].Year)=(@Year-1)) AND (([VHours].Period)>1))
) AS Jan
FROM dbo.tbl_RegionOffice AS O
END
RETURN

SELECT O.Region, O.Description, coalesce((SELECT (Sum( coalesce([VSeverity].[CountOfSeverity],0) )*100000)/Sum([VHours].[Total]) AS AFR
FROM [VHours] LEFT JOIN VSeverity ON ([VHours].Unit_Office = VSeverity.Unit_Office) AND ([VHours].Year = VSeverity.Year) AND ([VHours].Period = VSeverity.Period)
WHERE ((([VHours].Unit_Office)= O.Description) AND (([VHours].Year)=@Year) AND (([VHours].Period)<=1)) OR ((([VHours].Unit_Office)= O.Description) AND (([VHours].Year)=(@Year-1)) AND (([VHours].Period)>1))
),0) AS Jan
FROM dbo.tbl_RegionOffice AS O
