motorvehicletyperevenuepointchrage.ChargeID,
motorvehicletyperevenuepointchrage.AgencyID,
motorvehicletyperevenuepointchrage.RevenuePointID,
motorvehicle.MotorVehicleTypeEntryID,
motorvehiclecharge.Description,
motorvehiclecharge.AccountNumber,
officeunitbookaccount.OfficeUnitID
FROM
motorvehicle
INNER JOIN
motorvehicletyperevenuepointchrage
ON
motorvehicle.MotorVehicleTypeEntryID = motorvehicletyperevenuepointchrage.MotorVehicleTypeEntryID
INNER JOIN
motorvehiclecharge
ON
motorvehicletyperevenuepointchrage.ChargeID = motorvehiclecharge.ChargeID
INNER JOIN
officeunitbookaccount
ON
motorvehiclecharge.AccountNumber = officeunitbookaccount.AccountNumber
WHERE
motorvehicle.MotorVehicleTypeEntryID = motorvehicletyperevenuepointchrage.MotorVehicleTypeEntryID AND
motorvehicle.AgencyID = motorvehicletyperevenuepointchrage.AgencyID AND
motorvehicle.RevenuePointID = motorvehicletyperevenuepointchrage.RevenuePointID AND
motorvehicle.UVN = '1901/1907-04946'

I'm not sure this is correct or not.
