是微小的相對彼此的，如'22內：56.7 - 22：57.7'或相同的絕對分鐘'22內：56.0 - 22：57.0'？ –

它應該在絕對分鐘'22：56.0 - 22：57.0' – RanPaul

只是一個建議，你可以考慮設置[小提琴]（http://sqlfiddle.com/），讓人們更容易測試答案。 –

select cast(dt as date), datepart(hh, dt), datepart(mm, dt), datepart(ss,dt) 
    , count(*) 
from table 
group by cast(dt as date), datepart(hh, dt), datepart(mm, dt), datepart(ss,dt) 
order by count(*) desc

select TOP 1 myID,DateWithMinute from 
(select count(ID) as myID,convert(varchar(16),createdat,120) as DateWithMinute 
from yourtable 
group by convert(varchar(16),createdat,120) 
order by count(ID) desc)
