Null, not null SQL return
Hello all
I am trying to run a sql statement, (without having to run stored procedures), that will lookup a value stored in a Record.field., otherwise ignore the value if it is blank. I have a field tied to a Microsoft Access form - ItemLocation. If the user selects a unique ItemLocation the report will attempt to locate all values within that ItemLocation. If the user decides to leave the field blank, I would like for it to return all values for every ItemLocation. If anyone can help, I would really appreciate it. I will attach code. My problem is the last line of this SQL statement. If F.ITemLocation is null, I get no data. I would like for it to return everything. Thank you.
Code:
SELECT DISTINCT
B.BarCodeID,
A.ItemDescription,
A.ItemCategory,
A.TypeOfItem,
A.SerialNumber,
B.ItemLocation,
B.LocationID,
B.LastUpdate,
B.TrackItID,
B.UserID
FROM
tblMISFixedAssetTable A,
tblMISFixedAssetTable2 B
WHERE A.BarCodeID = B.BarCodeID
AND A.DisposalDate is null
AND B.LastUpdate = (Select Max(C.LastUpdate)
from tblMISFixedAssetTable2 C
Where B.BarCodeID = C.BarCodeID)
AND B.BarCodeID in (Select D.BarCodeID
from tblMISFixedAssetTable3 D
Where D.FiscalYear = (Select E.FiscalYear
from tblReportFY E))
AND B.ItemLocation = (Select F.ItemLocation
from tblReportFY F)

I don't know much about access so don't blame me if this does not work
