MySQL 如何仅显示小时和分钟

要仅显示小时和分钟，请使用DATE_FORMAT()，并在下面的语法中设置格式说明符−

select date_format(yourColumnName,'%H:%i') as anyAliasName from yourTableName;

让我们首先创建一张表−

mysql> create table DemoTable1527
  -> (
  -> ArrivalDatetime datetime
  -> );
Query OK, 0 rows affected (0.76 sec)

使用insert命令将一些记录插入到表中−

mysql> insert into DemoTable1527 values('2019-01-10 12:34:45');
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable1527 values('2018-12-12 11:00:34');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable1527 values('2019-03-21 04:55:56');
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 DemoTable1527;

这将产生以下输出−

+---------------------+
| ArrivalDatetime     |
+---------------------+
| 2019-01-10 12:34:45 |
| 2018-12-12 11:00:34 |
| 2019-03-21 04:55:56 |
+---------------------+
3 rows in set (0.00 sec)

以下是显示仅小时和分钟的查询−

mysql> select date_format(ArrivalDatetime,'%H:%i') as HourAndMinutes from DemoTable1527;

这将产生以下输出−

+----------------+
| HourAndMinutes |
+----------------+
| 12:34          |
| 11:00          |
| 04:55          |
+----------------+
3 rows in set (0.00 sec)
