GROUP BY VEHICLE_ID, DRIVER_ID 

TODATE我想選擇日期

Answer 1

之間ODOMETER如果里程錶是真正的里程錶讀數，然後這應該工作：的

SELECT 
VEHICLE_ID, 
DRIVER_ID, 
SUM(AMOUNT) as Total_Amount, 
MAX(ODOMETER) - MIN(ODOMETER) as DistanceTravelled, 
SUM(LTR) As Total_Ltr 
FROM Fuel_Filling 
WHERE 
COMPANY_ID = @COMPANY_ID 
AND VEHICLE_ID = @VEHICLE_ID 
AND DATE_TIME BETWEEN @FROM_DATE AND @TO_DATE 
GROUP BY VEHICLE_ID, DRIVER_ID
