我怎麼能A組水平的結果設置爲垂直的一象下面這樣：

Question

Select * from Machines Where DayOfWeight = '2013-10-31' 

退貨

MachineId TotalValue DayOfWeigh 
1   290.70  2013-10-31 
2   647.20  2013-10-31 
3   2178.56  2013-10-31 

我怎樣才能得到它返回：

DayOfWeigh 1  2  3 
2013-10-31 290.70 647.20 2178.56 

這似乎很簡單，但我無法找到正確的分組聲明或關鍵點？

Answer 1

select * 
from machines 
pivot (sum(TotalValue) for MachineID in ([1],[2],[3])) p

Answer 2

這個固定它

SELECT * 
FROM (
    SELECT 
     DayOfWeigh ,MachineId, TotalValue 
    FROM MachineTotals 
) as s 
PIVOT 
(
    SUM(TotalValue) 
    FOR MachineId IN ([1], [2], [3) 
)AS p
