透視和逆透視與TSQL

Question

多列的表，我需要轉動這個表看起來像這樣： my current table

我需要的是有13列的表，看起來像這樣： desired pivoted table 我使用tsql RazorSQL。這是我的代碼，導致決賽桌，現在需要進行調整。 ：

select s5.datess, ISNULL(s5.Active_And_Good,0) AS Active_And_Good, ISNULL(s5.Inactive_And_Good,0) AS Inactive_And_Good, 
    ISNULL(s5.Active_And_Bad,0) AS Active_And_Bad, ISNULL(s6.Inactive_And_Bad,0) AS Inactive_And_Bad 
      from 
      (select s3.dates as datess, s3.#Active_Good as Active_And_Good, s3.#Inactive_Good as Inactive_And_Good, 
    s4.Active_Bad as Active_And_Bad from 
    (select s1.Dates as dates, s1.Active_Good as #Active_Good, s2.Inactive_Good as #Inactive_Good from 
    (select count(DISTINCT Customer_Id) as Active_Good, Dates 
    from #fact_table 
    where Customer_Status = 1 
    group by Dates) as s1 
    full outer join 
    (select count(DISTINCT Customer_Id) as Inactive_Good, Dates 
    from #fact_table 
    where Customer_Status = 2 
    group by Dates) as s2 
    on s1.Dates=s2.Dates) as s3 
    full outer join 
    (select count(DISTINCT Customer_Id) as Active_Bad, Dates 
    from #fact_table 
    where Customer_Status = 3 
    group by Dates) as s4 
    on s3.dates= s4.Dates) as s5 
    full outer join 
    (select count(DISTINCT Customer_Id) as Inactive_And_Bad, Dates 
    from #fact_table 
    where Customer_Status = 4 
    group by Dates) as s6 
    on s5.datess= s6.Dates ; 

Answer 1

這應該有效。在您提供的表格的縮減版本上進行測試。

Create table #test ([datess] date, [Active_AndGood] int, [Inactive_And_Good] int) 
insert into #test ([datess],[Active_AndGood],[Inactive_And_Good]) 
values('2015-01-31',1,4) , ('2015-02-28',2,3) 

select * 
from #test 
unpivot (value for name in ([Active_AndGood],[Inactive_And_Good])) up 
pivot (max(value) for datess in ([2015-01-31],[2015-02-28])) p 

產生以下：

每當我需要樞軸或逆透視，我來看看這些鏈接刷新我的這些事情是如何工作的內存。
