如何将小时数转换为天数 - MYSQL

Question

如果我有一个开始时间和结束时间，并且我找到总时间，如果超过24小时，我希望它而不是显示26，显示1天和2小时。如何才能做到这一点？

Answer 1

你可能想做一个

IF    (MOD(HOUR(TIME) / 24) )  > 24, 
    SELECT CONCAT(
    FLOOR(HOUR(TIME) / 24), ' days ',
    MOD(HOUR(TIME), 24), ' hours ',
    MINUTE(TIME), ' minutes')
)

随着Timediff，

FLOOR(HOUR(TIMEDIFF('2010-01-06 08:46', '2010-01-01 12:30')) / 24), ' days ',

Answer 2

如果你的start_time和end_time是日期时间类型，那么使用TIMEDIFF函数并应用所需的DATE_FORMAT。

EG

select DATE_FORMAT(TIMEDIFF('2012:01:01 00:00:00', '2012:01:01 00:00:00.000001'),
                  '%d: %H: %m');

Answer 3

这对我有用：

select
   o.id,
   o.created,
   o.complete_date,
   concat(timestampdiff(day, o.created, o.complete_date),
          'd ',
          lpad(
             mod(timestampdiff(hour, o.created, o.complete_date), 24),
             2, '0'),
          'h'
   ) as time_to_complete,
from
   orders o
;

结果：

+---------+---------------------+---------------------+------------------+
| id      | created             | complete_date       | time_to_complete |
