Answer 1

簡単な条件の集約でのCROSS APPLYとのコンサートはトリックを行うべきです

Declare @YourTable table ([Task] int,[Start] datetime,[End] datetime,[People] int) 
Insert Into @YourTable values 
(1,'2017-03-17 02:00:00','2017-03-17 08:00:00',10) 
,(2,'2017-03-17 02:00:00','2017-03-17 08:00:00',5) 
,(3,'2017-03-17 03:00:00','2017-03-17 05:00:00',8) 
,(4,'2017-03-17 04:00:00','2017-03-17 06:00:00',10) 

Select [01:00] = sum(case when DatePart(HOUR,D)=1 then People else 0 end) 
     ,[02:00] = sum(case when DatePart(HOUR,D)=2 then People else 0 end) 
     ,[03:00] = sum(case when DatePart(HOUR,D)=3 then People else 0 end) 
     ,[04:00] = sum(case when DatePart(HOUR,D)=4 then People else 0 end) 
     ,[05:00] = sum(case when DatePart(HOUR,D)=5 then People else 0 end) 
     ,[06:00] = sum(case when DatePart(HOUR,D)=6 then People else 0 end) 
     ,[07:00] = sum(case when DatePart(HOUR,D)=7 then People else 0 end) 
     ,[08:00] = sum(case when DatePart(HOUR,D)=8 then People else 0 end) 
     ,[09:00] = sum(case when DatePart(HOUR,D)=9 then People else 0 end) 
From @YourTable 
Cross Apply (Select Top (DateDiff(HOUR,[Start],[End])+1) D=DateAdd(HOUR,-1+Row_Number() Over (Order By (Select Null)),[Start]) 
       From master..spt_values n1,master..spt_values n2 
      ) B

Answer 2

あなたは以下のようにこれを取得するために時間、集計テーブルとピボットを使用することができます。以下のように

select ISNULL([1],0) as [1:00:00], [2] as [2:00:00],[3] as [3:00:00], [4] as [4:00:00],[5] as [5:00:00] 
,[6] as [6:00:00],[7] as [7:00:00],[8] as [8:00:00],ISNULL([9],0) as [9:00:00] 
from (
    select Hrs= Datepart(hour,RowN),SmPeople= sum(people) from Yourtask 
    cross apply (
     select top (datediff(hour, [start],[end])+1) RowN= DateAdd(hour, row_number() over (order by (Select null))-1, [Start]) 
      from master..spt_values n1, master..spt_values n2 
    ) a 
    group by Datepart(hour,RowN) 
) CalcuatedPeople 
pivot (max(SmPeople) for hrs in ([1],[2],[3],[4],[5],[6],[7],[8],[9])) p 

出力：
