在MySQL中创建表并实现TIMESTAMPDIFF()？

2024-05-02 12:47:03 447

该TIMESTAMPDIFF()计算两个日期或日期时间表达式之间的差异。让我们首先创建一个表-

mysql> create table DemoTable665(
   PunchInTime datetime,
   PunchOutTime datetime,
   Details INT(11) AS (ABS(TIMESTAMPDIFF(second,PunchInTime,PunchOutTime)))
)ENGINE=MyISAM;

使用插入命令在表中插入一些记录-

mysql> insert into DemoTable665(PunchInTime,PunchOutTime) values('2019-09-21 9:30:10','2019-09-21 04:34:56');
mysql> insert into DemoTable665(PunchInTime,PunchOutTime) values('2019-11-11 10:00:20','2019-11-11 05:30:16');

使用select语句显示表中的所有记录-

mysql> select *from DemoTable665;

这将产生以下输出-

+---------------------+---------------------+---------+
| PunchInTime         | PunchOutTime        | Details |
+---------------------+---------------------+---------+
| 2019-09-21 09:30:10 | 2019-09-21 04:34:56 | 17714   |
| 2019-11-11 10:00:20 | 2019-11-11 05:30:16 | 16204   |
+---------------------+---------------------+---------+
2 rows in set (0.00 sec)
