如何在MySQL中仅显示小时和分钟？
要仅显示小时和分钟，请使用DATE_FORMAT()并按照以下语法设置格式说明符-
select date_format(yourColumnName,'%H:%i') as anyAliasName from yourTableName;
让我们首先创建一个表-
mysql> create table DemoTable1527 -> ( -> ArrivalDatetime datetime -> );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable1527 values('2019-01-10 12:34:45');
mysql> insert into DemoTable1527 values('2018-12-12 11:00:34');
mysql> insert into DemoTable1527 values('2019-03-21 04:55:56');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)
以下是仅显示小时和分钟的查询-
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)
