Question

我有五个输出（这是查询TIMEDIFF(out_time, in_time)） - ＆gt; 9:04:04, 8:56:16, 9:43:09, 9:40:03

当我使用此SUM(TIMEDIFF(out_time, in_time)) as 'Working hours'查询获取此次总和时，我会得到 364332 ，但我想要的是时间格式 37:23:32 是有没有代码要做？

Answer 1

您可以使用MySQL函数SEC_TO_TIME()

SELECT SEC_TO_TIME(SUM(TIMEDIFF(out_time, in_time))) as Working hours

Answer 2

试试这个：

select DATE_FORMAT(FROM_UNIXTIME(SUM(TIMEDIFF(out_time, in_time))) ,'%H:%i:%s') as 'Working hours'

Answer 3

试试这个：

Select SEC_TO_TIME(SUM(TIME_TO_SEC(timediff(out_time, in_time)))) AS workingHours

Answer 4

这是我做了它的工作

CONCAT(
FLOOR(
SUM(CASE WHEN TIME_TO_SEC(TIMEDIFF(out_time,in_time))<=0 THEN TIME_TO_SEC(TIMEDIFF(out_time,in_time))=''
ELSE TIME_TO_SEC(TIMEDIFF(out_time,in_time)) END)/3600) ,':',
FLOOR(MOD(
SUM(CASE WHEN TIME_TO_SEC(TIMEDIFF(out_time,in_time))<=0 THEN TIME_TO_SEC(TIMEDIFF(out_time,in_time))=''
ELSE TIME_TO_SEC(TIMEDIFF(out_time,in_time)) END),3600)/60)) as 'WORKING HOURS'

如何在mysql中转换时间格式？
