Select a driver being used for first time
Feb 28 2012 5:15 AM
Got 2 tables, drivers and AllocatedHistory
i have to select a driver thats being allocated for the first time to a vehicle.
So it has to be like where entry is only 1 or less than 2. because when he is allocated, an entry will be generated in the allocation table.
Select tblU.UserID
From
Users tblU
Where

(select Count(tblU.UserID) as ID
From
AllocatedHistory tblH
Where
