using DateDiff to find duration in minutes

Question

I am trying to use Datediff to find out the duration between columnA and columnB .

SELECT datediff (minute, stime, etime)
from Exceptions2
where stime = [exceptions2].starttime
and etime = [exceptions2].endtime

This produces errors. Can anyone please help me with what I'm doing wrong?

Answer 1

如何尝试这个，不知道为什么你有stime = [exceptions2] .starttime和etime = [exceptions2] .endtime

SELECT datediff(minute, starttime, endtime) from Exceptions2
