枢轴两柱对于SQL

Question

，我有以下数据：

--------------------------------------------------- 
oGroup  oDate  Value1  Value2 
--------------------------------------------------- 
A   2014-01-01 10   100 
A   2014-01-02 12   108 
B   2014-01-01 20   120 
B   2014-01-02 22   140 
C   2014-01-01 5   160 
C   2014-01-02 9   175 

我有枢轴以下脚本：

select 
    * 
from 
    (
    select 
     Group 
     , oDate 
     , Value1 
     , Value2 
    from #ret 
    ) src 
    pivot 
    (
     sum(value1) 
     for group in ([X1], [X2], [X3]) 
    ) piv 
    order by oDate; 

那么结果应该是这样的：

------------------------------------------------ 
oDate   X1  X2  X3 
------------------------------------------------ 
2014-01-01 10  20  5 
2014-01-02 12  22  9 

我的问题是我怎样才能将value2添加到X1，X2，X3之后的另外3列。比方说，Y1 Y2和Y3。

所以结果应该是：

------------------------------------------------------ 
oDate   X1  X2  X3  Y1  Y2  Y3 
------------------------------------------------------ 
2014-01-01 10  20  5  100 120 160 
2014-01-02 12  22  9  108 140 175 
------------------------------------------------------ 

我怎样才能做到这一点？谢谢。

Answer 1

PIVOT随着：

DECLARE @t TABLE 
    (
     oGroup CHAR(1) , 
     oDate DATE , 
     Value1 INT , 
     Value2 INT 
    ) 

INSERT INTO @t 
VALUES ('A', '20140101', 10, 100), 
     ('A', '20140102', 12, 108), 
     ('B', '20140101', 20, 120), 
     ('B', '20140102', 22, 140), 
     ('C', '20140101', 5, 160), 
     ('C', '20140102', 9, 175); 
WITH cte1 
      AS (SELECT oGroup , 
         oDate , 
         Value1 
       FROM  @t 
      ), 
     cte2 
      AS (SELECT oGroup , 
         oDate , 
         Value2 
       FROM  @t 
      ) 
    SELECT a1.* , 
      a2.[A] , 
      a2.[B] , 
      a2.[C] 
    FROM (SELECT * 
       FROM  cte1 PIVOT(SUM(Value1) FOR oGroup IN ([A], [B], 
                  [C])) AS p 
      ) a1 
      JOIN (SELECT * 
        FROM  cte2 PIVOT(SUM(Value2) FOR oGroup IN ([A], 
                  [B], [C])) AS p 
       ) a2 ON a1.oDate = a2.oDate 

输出：

oDate  A B C A B C 
2014-01-01 10 20 5 100 120 160 
2014-01-02 12 22 9 108 140 175 

Answer 2

select 
    * 
into #tb1 
from 
    (
    select 
     Group 
     , oDate 
     , Value1 
    from #ret 
    ) src 
    pivot 
    (
     sum(value1) 
     for group in ([X1], [X2], [X3]) 
    ) piv 
    order by oDate; 

select 
    * 
into #tb2 
from 
    (
    select 
     Group 
     , oDate 
     , Value2 
    from #ret 
    ) src 
    pivot 
    (
     sum(value2) 
     for group in ([Y1], [Y2], [Y3]) 
    ) piv 
    order by oDate; 



select * from #tb1 inner join #tb2 on #tb1.oDate = #tb2.oDate
