Hi?
My select, which I will make into a stored procedure.
Produces the correct number or rows,in the result table the UseId field and the IsEstimate field and NoteCode field are empty, now I want to just return those rows???
I tried using NULL in my condition but no rows were returned???

--- this is my query ---


declare @AreaId int, @SuburbId int, @CalcDate datetime
set @SuburbId = 8
set @AreaId = 1
set @CalcDate = '2012/11/01'

select UseId, S.SuburbId, count (*) as Tot,

M.LastCloseReading,
M.LastReadingDate,
M.LastUsage,
M.MeterNo,
S.Key21,

U.IsEstimate,
U.NoteCode,
U.AccessCode
from mlmStand S
join mlmMeter M
on S.StandId = M.StandId
and TypeId = 0
and Disabled = 0
and S.AreaId = @AreaId
and S.SuburbId = @SuburbId
left join mlmMeterUsage U
on M.MeterId = U.MeterId
and U.CalcDate = @CalcDate
/*
and U.IsEstimate = null
and U.NoteCode = null
and U.AccessCode = null
*/
group by S.SuburbId, LastCloseReading, LastReadingDate, M.LastUsage, M.MeterNo, S.Key21, U.IsEstimate, U.NoteCode, U.AccessCode, UseId

order by U.UseId


--- this is the result set ---

You'll notice the first 5 rows have no UseId, IsEstimate, NoteCode, AccessCode, I want to just return those five rows

UseId SuburbId Tot Reading Reading LastUsage MeterNo Key21 IsEstimate NoteCode AccessCode

You can't use = null, but you can use:

WHERE UseId IS NULL
