让我们首先创建一个表-mysql> create table DemoTable845(AdmissionDate date);
使用插入命令在表中插入一些记录-mysql> insert into DemoTable845 values('2018-01-21');
mysql> insert into DemoTable845 values('2016-12-12');
mysql> insert into DemoTable845 values('2019-08-05');
mysql> insert into DemoTable845 values('2019-10-15');
使用select语句显示表中的所有记录-mysql> select *from DemoTable845;
这将产生以下输出-+---------------+
| AdmissionDate |
+---------------+
| 2018-01-21 |
| 2016-12-12 |
| 2019-08-05 |
| 2019-10-15 |
+---------------+
4 rows in set (0.00 sec)
以下是将YYYY-MM-DD转换为DD月，YYYY日期格式的查询-mysql> select date_format(AdmissionDate,'%e %M, %Y') from DemoTable845;
这将产生以下输出-+----------------------------------------+
| date_format(AdmissionDate,'%e %M, %Y') |
+----------------------------------------+
| 21 January, 2018 |
| 12 December, 2016 |
| 5 August, 2019 |
| 15 October, 2019 |
