格式化MySQL日期并转换为年-月-日
让我们首先创建一个表-
mysql> create table DemoTable666(AdmissionDate varchar(200));
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable666 values('Sat,20 Jul 2019 04:29:35');mysql> insert into DemoTable666 values('Fri,02 Oct 2018 12:19:15');
mysql> insert into DemoTable666 values('Sun,01 Aug 2016 11:10:05');
mysql> insert into DemoTable666 values('Fri, 06 Nov 2015 04:06:05 -0500');
使用select语句显示表中的所有记录-
mysql> select *from DemoTable666;
这将产生以下输出-
+---------------------------------+| AdmissionDate |
+---------------------------------+
| Sat,20 Jul 2019 04:29:35 |
| Fri,02 Oct 2018 12:19:15 |
| Sun,01 Aug 2016 11:10:05 |
| Fri, 06 Nov 2015 04:06:05 -0500 |
+---------------------------------+
4 rows in set (0.00 sec)
以下是将上述日期格式转换为年月日的查询-
mysql> select DATE_FORMAT(STR_TO_DATE(AdmissionDate, '%a, %d %b %Y %H:%i:%S'),'%Y-%m-%d %H:%i:%s') AS MyDate from DemoTable666;
这将产生以下输出-
+---------------------+| MyDate |
+---------------------+
| 2019-07-20 04:29:35 |
| 2018-10-02 12:19:15 |
| 2016-08-01 11:10:05 |
| 2015-11-06 04:06:05 |
+---------------------+
