I have a query set up that returns the data that I would like, but I
would only like the latest data for each vehicle number. The query I
have set up is

SELECT TOP 100 PERCENT dbo.vwEvents.EventName,
dbo.luSessionAll.SessionName, dbo.luOuting.OutingNumber,
dbo.luVehicle.VehicleName, dbo.luOuting.OutingID,
dbo.tblOutings.OutingStartTime,dbo.tblSessions.SessionDate,dbo.tblSessions.SessionStartTime
FROM dbo.vwSessions INNER JOIN dbo.vwEvents ON
dbo.vwSessions.Event = dbo.vwEvents.EventID
INNER JOIN
dbo.luSessionAll ON dbo.vwEvents.EventID =
dbo.luSessionAll.Event INNER JOIN
dbo.luOuting ON dbo.luSessionAll.SessionID =
dbo.luOuting.SessionID INNER JOIN
dbo.luVehicle ON dbo.luSessionAll.Vehicle =
dbo.luVehicle.VehicleID INNER JOIN
dbo.tblOutings ON dbo.luOuting.OutingID =
dbo.tblOutings.OutingID INNER JOIN
dbo.tblSessions ON dbo.tblOutings.[Session] =
dbo.tblSessions.SessionID
GROUP BY dbo.vwEvents.EventName, dbo.luSessionAll.SessionName,
dbo.luOuting.OutingNumber, dbo.luVehicle.VehicleName,
dbo.luOuting.OutingID, dbo.tblOutings.OutingStartTime,
dbo.tblSessions.SessionStartTime, dbo.tblSessions.SessionDate
ORDER BY dbo.luVehicle.VehicleName, dbo.tblSessions.SessionDate,
dbo.tblSessions.SessionStartTime, dbo.tblOutings.OutingStartTime

this returns all the outings. I would like the outing that has, in
order of importance, the latest session date, latest session time and
latest outing start time. Outing start time can sometimes be <<Null>>
but the other two always have values. How would I go about doing this?
thanks in advance for any help
