MySQL DATE_FORMAT '%M' 用于短月份?
mysqlmysqli database
%M 日期格式不用于显示短月份，例如 Jan 表示一月、Feb 表示二月等。您需要使用 DATE_FORMAT() 函数和 %b 格式来显示短月份。语法如下:
SELECT DATE_FORMAT(yourColumnName, '%d-%b-%y') AS anyVariableName FROM yourTableName;
为了理解上述语法，让我们创建一个表。创建表的查询如下:
mysql> create table DateFormatMonthDemo -> ( -> Id int NOT NULL AUTO_INCREMENT, -> ShippingDate date, -> PRIMARY KEY(Id) -> ); Query OK, 0 rows affected (0.63 sec)
使用 insert 命令在表中插入一些记录。插入记录的查询如下:
mysql> insert into DateFormatMonthDemo(ShippingDate) values('2019-05-21');
Query OK, 1 row affected (0.23 sec)
mysql> insert into DateFormatMonthDemo(ShippingDate) values('2015-05-23');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DateFormatMonthDemo(ShippingDate) values('2019-11-01');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DateFormatMonthDemo(ShippingDate) values('2017-12-24');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DateFormatMonthDemo(ShippingDate) values('2016-01-13');
Query OK, 1 row affected (0.19 sec)
mysql> insert into DateFormatMonthDemo(ShippingDate) values('2015-02-22');
Query OK, 1 row affected (0.19 sec)
使用 select 语句显示表中的所有记录。查询如下:
mysql> select *from DateFormatMonthDemo;
+----+--------------+ | Id | ShippingDate | +----+--------------+ | 1 | 2019-05-21 | | 2 | 2015-05-23 | | 3 | 2019-11-01 | | 4 | 2017-12-24 | | 5 | 2016-01-13 | | 6 | 2015-02-22 | +----+--------------+ 6 rows in set (0.00 sec)
以下是显示短月份名称的查询:
mysql> select DATE_FORMAT(ShippingDate, '%d-%b-%y') AS DateDemo from DateFormatMonthDemo;
输出结果如下:
+-----------+ | DateDemo | +-----------+ | 21-May-19 | | 23-May-15 | | 01-Nov-19 | | 24-Dec-17 | | 13-Jan-16 | | 22-Feb-15 | +-----------+ 6 rows in set (0.04 sec)
