如何排隊

Question

我有被這樣創建的數據透視表數據透視表的列：

date Services Uptime  Services Downtime Centers Downtime Centers Uptime 
----- --------- -  ------------------ ---------------- --------------- 
12/5/14  100.00%    0.00%     100.00%  100.00%  
12/12/14  100.00%    0.00%      0.00%   0.00% 
12/19/14  100.00%    0.00%     100.00%  0.00% 
12/26/14  100.00%    0.00%     100.00%   0.00% 

我想它出來的數據透視表，就像這樣：

Date   Name    Uptime    Downtime 
-----  ------   ---------   ------------- 
12/5/14  Services    100.00%     0.00% 
12/5/14  Center    100.00%    100.00% 
12/12/14 services    100.00%     0.00% 
12/12/14 Center     0.00%     0.00% 

Answer 1

可能是您需要unpivot而不是pivoting。我會用cross apply和tables valued constructor來做到這一點。

明智的性能，這將是比Union All如果你有更多的names

SELECT [date],NAME, uptime, downtime 
FROM Yourtable 
     CROSS apply (VALUES ('service',Services_Uptime,Services_Downtime), 
          ('center',Centers_Uptime,Centers_Downtime)) 
        cs (NAME, uptime, downtime) 

Answer 2

如果只有那些2倍的值，嘗試UNION：

select [date] 
     ,'Services' 
     ,[Services Uptime] as Uptime 
     ,[Services Dowtime] as Downtime 
from myTable 
union all 
select [date] 
     ,'Center' 
     ,[Centers Uptime] as Uptime 
     ,[Centers Dowtime] as Downtime 
from myTable
