sql编写场景，

有个车辆进出表，需查出车辆进出时间

id	carNo	time	flag
1	车001	2021-12-16 14:00:05	1
2	车001	2021-12-16 16:00:06	0
3	车002	2021-12-16 15:00:05	1
4	车002	2021-12-16 17:00:07	0
5	车003	2021-12-16 15:00:05	1
6	车003	2021-12-16 16:00:08	0

 

 

 

 

 

 

 

 

希望查询结果

carNo	enter_time	out_time
车001	2021-12-16 14:00:05	2021-12-16 16:00:06
车002	2021-12-16 15:00:05	2021-12-16 17:00:07
车003	2021-12-16 15:00:05	2021-12-16 16:00:08

 

 

 

 

 

SELECT
	t1.carNo,
	t1.time AS enter_time,
	(
		SELECT
			t2.time 
		FROM
			car t2 
		WHERE
			t2.flag = '0' 
			AND t1.carNo = t2.carNo 
			AND t2.time > t1.time 
			LIMIT 1 
	) AS out_time 
FROM
	car t1 
WHERE
	t1.flag = '1';

 具体SQL为：

select t1.carNo, t1.time,
