时间：mysql如何时间戳排序

mysql如什么时候间戳排序

mysql中实现按时间戳排序的方法

1.首先，首先创建一个数据表；

create table DemoTable
(
`timestamp` varchar(100)
);

2.数据表创建好后，向表中插入时间戳数据；

insert into DemoTable values('06/22/2019 01:10:20 PM');
insert into DemoTable values('06/22/2019 12:00:27 PM');
insert into DemoTable values('06/22/2019 06:56:20 AM');
insert into DemoTable values('06/22/2019 07:10:11 AM');

3.时间戳数据插入后，查看表结构；

select *from DemoTable;
+------------------------+
| timestamp |
+------------------------+
| 06/22/2019 01:10:20 PM |
| 06/22/2019 12:00:27 PM |
| 06/22/2019 06:56:20 AM |
| 06/22/2019 07:10:11 AM |
+------------------------+
4 rows in set (0.00 sec)

4.通过履行以下命令对表中的时间戳进行排序；

select *from DemoTable ORDER BY STR_TO_DATE(`timestamp`,'%m/%d/%Y%h:%i:%s %p');

5.最后，时间戳排序好后，继续查看表结构，便可看到时间戳排序成功；

select *from DemoTable;
+------------------------+
| timestamp |
+------------------------+
| 06/22/2019 06:56:20 AM |
| 06/22/2019 07:10:11 AM |
| 06/22/2019 12:00:27 PM |
| 06/22/2019 01:10:20 PM |
+------------------------+
4 rows in set (0.00 sec)
