Hi LU,
Without knowing your table structure, sample data and expected output,
the best I can offer is a wild guess:
SELECT Units.UnitServiceLine, Units.UnitName,
Staffing_Types.StaffingType, Unit_Request.UnitOnDutyStaff,
PS.SumOfPrivateIDs
FROM Unit_Info
INNER JOIN Unit_Request
ON Unit_Info.UIID = Unit_Request.UIID
INNER JOIN Units
ON Unit_Info.UnitID = Units.UID
INNER JOIN Staffing_Types
ON Unit_Request.STID=Staffing_Types.STID
INNER JOIN (SELECT UIID, SUM(PrivateIDs) AS SumOfProvateiDs
FROM Private
GROUP BY UIID) AS PS
ON Unit_Info.UIID = PS.UIID
(untested)
If this doesn't help, then check www.aspfaq.com/5006, then post again,
following the instructions therein.
Best, Hugo
