如何以小时和分钟为单位获得两个日期时间之间的差异

How to get the difference between those datetimes in the following format :

hh:mm

<小时>

我用

DATEDIFF(hour, transtime_in, transtime_out) 

但我只有小时数.

推荐答案

试试这个 -

查询:

DECLARE 
      @transtime_in DATETIME
    , @transtime_out DATETIME

SELECT 
      @transtime_in = '2013-05-19 08:58:07.000'
    , @transtime_out = '2013-05-19 16:40:53.000'

SELECT LEFT(CONVERT(VARCHAR(10), @transtime_out - @transtime_in, 108), 5)

输出:

-----
07:42
