MySQL 如何使用DATE_FORMAT()更改日期格式

您可以使用DATE_FORMAT()使用特定格式更改MySQL日期格式。以下是语法−

select date_format(yourColumnName,yourFormatSpecifier) from yourTableName;

让我们首先创建一个表−

mysql> create table DemoTable
   (
   ShippingDate date
   );
Query OK, 0 rows affected (0.48 sec)

使用insert命令向表中插入一些记录 −

mysql> insert into DemoTable values('2016-01-21');
Query OK, 1 row affected (0.17 sec)

mysql> insert into DemoTable values('2018-05-24');
Query OK, 1 row affected (0.18 sec)

mysql> insert into DemoTable values('2019-12-31');
Query OK, 1 row affected (0.18 sec)

使用select语句显示表中的所有记录−

mysql> select *from DemoTable;

这将产生以下输出−

+--------------+
| ShippingDate |
+--------------+
| 2016-01-21   |
| 2018-05-24   |
| 2019-12-31   |
+--------------+
3 rows in set (0.00 sec)

以下是在MySQL查询中实现DATE_FORMAT()并设置日期格式的查询−

mysql> select date_format(ShippingDate,'%d/%m/%Y') from DemoTable;

这将产生以下输出−

+--------------------------------------+
| date_format(ShippingDate,'%d/%m/%Y') |
+--------------------------------------+
| 21/01/2016                           |
| 24/05/2018                           |
| 31/12/2019                           |
+--------------------------------------+
3 rows in set (0.00 sec)
