我想获取所有的驱动程序列表，

   attendance.atdnc_date <> '2018-11-17' AND attendance.isleave<>1

    OR that attendance row is null according to driver
AND 
vehicle_status.current_status = 'cancelled' OR vehicle_status.current_status = 'completed'
OR, OR that vehicle_status row is null according to driver

在这里我尝试查询：

1）

SELECT * FROM
(SELECT driver.* FROM driver LEFT JOIN (SELECT vehicle.* FROM vehicle_status INNER JOIN vehicle ON vehicle_status.vehicle_id=vehicle.vehicle_id WHERE current_status <> 'completed' AND current_status <> 'cancelled') k
 ON driver.driver_id=k.driver_id INNER JOIN(SELECT driver.driver_id FROM driver LEFT JOIN (SELECT emp_id FROM `attendance` WHERE isleave=1 AND atdnc_date='2018-11-17') as x ON x.emp_id=driver.driver_id WHERE x.emp_id IS NULL ) d ON driver.driver_id=d.driver_id ) as x

2）

SELECT * FROM driver 
LEFT JOIN vehicle ON driver.driver_id=vehicle.driver_id 
LEFT JOIN vehicle_status ON vehicle.vehicle_id=vehicle_status.vehicle_id 
LEFT JOIN attendance ON driver.driver_id=attendance.emp_id WHERE (vehicle_status.current_status ="completed" OR vehicle_status.current_status ="cancelled" OR vehicle_status.current_status IS NULL) 
AND ((attendance.atdnc_date = '2018-11-17' AND attendance.isleave = 0) OR (attendance.atdnc_date IS NULL) ) GROUP BY driver.driver_id

3）

SELECT * FROM (SELECT driver.* FROM driver LEFT JOIN (SELECT vehicle.* FROM vehicle_status INNER JOIN vehicle ON vehicle_status.vehicle_id=vehicle.vehicle_id WHERE current_status <> 'completed' AND current_status <> 'cancelled') k ON driver.driver_id=k.driver_id WHERE k.driver_id IS NULL) x 
INNER JOIN (SELECT driver.* FROM driver LEFT JOIN attendance ON driver.driver_id=attendance.emp_id WHERE ((attendance.atdnc_date <> '2018-11-17' AND attendance.isleave <> 0) OR (attendance.atdnc_date IS NULL) )) b ON x.driver_id=b.driver_id

我认为这是有效的..但是在使用大量数据时可能会很慢。 4）

  select  b.* FROM (SELECT driver.* FROM driver LEFT JOIN (SELECT vehicle.* FROM vehicle_status INNER JOIN vehicle ON vehicle_status.vehicle_id=vehicle.vehicle_id WHERE current_status <> 'completed' AND current_status <> 'cancelled') k 
ON driver.driver_id=k.driver_id WHERE k.driver_id IS NULL) b 
LEFT JOIN (SELECT driver.driver_id FROM attendance INNER JOIN driver ON attendance.emp_id=driver.driver_id WHERE attendance.atdnc_date='2018-11-17' AND attendance.isleave='1') k ON b.driver_id=k.driver_id 
  WHERE k.driver_id IS NULL  AND status ='1'

这些查询有时可以工作。但是当出勤率和vehicle_status与驾驶员有多行时，这些查询将失败。并显示多个驱动程序或显示不符合条件的驱动程序:(
