如何在MySQL中将DATETIME中的日期和时间分开？

要从DATETIME中分离出DATE和TIME，您可以使用MySQL的DATE_FORMAT()方法。语法如下 −

SELECT DATE_FORMAT(yourColumnName, '%Y-%m-%d') VariableName, DATE_FORMAT(yourColumnName,'%H:%i:%s') VariableName from yourTableName;登录后复制为了理解上述方法DATE_FORMAT()，让我们创建一个数据类型为“datetime”的表。

mysql> create table DateAndTimePartDemo -> ( -> YourDateandtime datetime -> ); Query OK, 0 rows affected (0.56 sec)登录后复制

mysql> insert into DateAndTimePartDemo values(now()); Query OK, 1 row affected (0.37 sec)登录后复制

mysql> select *from DateAndTimePartDemo;登录后复制

+---------------------+ | YourDateandtime | +---------------------+ | 2018-11-24 13:40:36 | +---------------------+ 1 row in set (0.00 sec)登录后复制

查询如下所示 −

mysql> SELECT DATE_FORMAT(YourDateandtime, '%Y-%m-%d') OnlyYourDate, -> DATE_FORMAT(YourDateandtime,'%H:%i:%s') OnlyYourTime from DateAndTimePartDemo;登录后复制

+--------------+--------------+ | OnlyYourDate | OnlyYourTime | +--------------+--------------+ | 2018-11-24 | 13:40:36 | +--------------+--------------+ 1 row in set (0.03 sec)登录后复制
