DROP TABLE IF EXISTS Attendances;
CREATE TABLE Attendances (id int, employee_id int, timedata datetime, in_out varchar(55));
INSERT INTO Attendances (id, employee_id, timedata, in_out) VALUES
(1, 1,'2017-06-07 19:25:10','OUT'),
(2, 1,'2017-06-08 09:25:17','IN'),
(3, 1,'2017-06-08 13:51:02','IN'),
(4, 1,'2017-06-08 20:44:14','OUT'),
(5, 1,'2017-06-09 01:10:04','OUT'),
(6, 1,'2017-06-09 14:11:40','IN'),
(7, 1,'2017-06-09 19:41:26','OUT'),
(8, 1,'2017-06-09 11:35:00','IN'),
(9, 1,'2017-06-09 20:36:06','OUT');
我的数据：
id employee_id timedata in_out
1 1 07.06.2017 19:25:10 OUT
2 1 08.06.2017 09:25:17 IN
3 1 08.06.2017 13:51:02 IN
4 1 08.06.2017 20:44:14 OUT
5 1 09.06.2017 01:10:04 OUT
6 1 09.06.2017 14:11:40 IN
7 1 09.06.2017 19:41:26 OUT
8 1 09.06.2017 11:35:00 IN
9 1 09.06.2017 20:36:06 OUT
我想将数据传输到带有结果的MySQL查询中：
employee_id time_in time_out
1 NULL 07.06.2017 19:25:10
1 08.06.2017 09:25:17 NULL
1 08.06.2017 13:51:02 08.06.2017 20:44:14
1 NULL 09.06.2017 01:10:04
1 09.06.2017 14:11:40 09.06.2017 19:41:26
1 09.06.2017 11:35:00 09.06.2017 20:36:06
