如何将两个日期之间的差异四舍五入到小时

Question

我将在下面的示例中说明我想要获得的内容:

'2010-09-01 03:00:00' - '2010-09-01 00:10:00'

使用TIMEDIFF(),我们得到2结果.这意味着,它没有考虑剩下的50分钟.

在这种情况下,我想得到的是:50(分钟)/ 60 = 0.83期间.因此,结果应该是2.83而不是2.

Answer 1

select time_to_sec(timediff('2010-09-01 03:00:00', '2010-09-01 00:10:00' )) / 3600;

+-----------------------------------------------------------------------------+
| time_to_sec(timediff('2010-09-01 03:00:00', '2010-09-01 00:10:00' )) / 3600 |
+-----------------------------------------------------------------------------+
|                                                                      2.8333 |

Answer 2

我认为更完整的答案是

select time_format(timediff(onedateinstring,anotherdateinstring),'%H:%i:%s')

这允许您以您想要的格式查看您希望看到的小时,分​​钟,秒等...

Answer 3

您可以尝试以下方法:

time_format(timediff(max(l.fecha), min(l.fecha) ),'%H:%m') //Hora y minutos

Answer 4

使用TIMESTAMPDIFF确切的小时数:

SELECT 
      b.`Start_Date`, 
      b.`End_Date`, 
      TIMESTAMPDIFF(HOUR, b.`Start_Date`, b.`End_Date`) AS `HOURS` 
FROM my_table b;

Answer 5

它是一个非常老的线程,但您也可以尝试TIMESTAMPDIFF并将MINUTE,HOUR,SECONDS作为限定符.

Answer 6

MySQL 获取时间戳之间的小时数：

select timestampdiff(second,'2010-09-01 00:10:00', '2010-09-01 03:00:00')/3600;
