樞軸2項措施的SQL Server

我需要做AGG_A的最大值，而不是通過轉動它。

如果我把它作爲一個維度，如當前代碼所示，它會產生意想不到的結果（隨機行數），因爲它實際上是一個度量。

目前代碼

Declare @Query_ nvarchar(MAX) 
Declare @Cols_For_Pivot_ nvarchar(MAX) 

--Get unique list of metrics in Var_Col for pivot. 
SELECT @Cols_For_Pivot_= COALESCE(@Cols_For_Pivot_ + ',','') + QUOTENAME(COL_D) 
FROM (SELECT DISTINCT COL_D FROM dbo.my_table) AS PivotTable 



SET @Query_ = 
    N'SELECT COL_A 
      ,COL_B 
      ,COL_C 
      ,AGG_A 
      , ' + @Cols_For_Pivot_ + ' 
    FROM dbo.min_by_min_static_results 
    PIVOT(SUM(AGG_B) 
      FOR COL_D IN (' + @Cols_For_Pivot_ + ')) AS P' 


--Execute dynamic query 
EXEC sp_executesql @Query_

所需的結果

SET @Query_ = 
    N'SELECT COL_A 
      ,COL_B 
      ,COL_C 
      ,MAX(AGG_A) 
      , ' + @Cols_For_Pivot_ + ' 
    FROM dbo.min_by_min_static_results 
    PIVOT(SUM(AGG_B), 
      FOR COL_D IN (' + @Cols_For_Pivot_ + ')) AS P'

的可能的複製[SQL Server的透視表具有多個列的聚集體（http://stackoverflow.com/questions/14694691/sql-server-pivot-table-with-multiple-column-aggregates） –

明白了，我只需要過的分區。

SET @Query_ = 
    N'SELECT COL_A 
      ,COL_B 
      ,COL_C 
      ,MAX(AGG_A) OVER(PARTITION BY 
            COL_A 
            ,COL_B 
            ,COL_C 
            , ' + @Cols_For_Pivot_ + ') AS AGG_A 
      , ' + @Cols_For_Pivot_ + ' 
    FROM dbo.min_by_min_static_results 
    PIVOT(SUM(AGG_B), 
      FOR COL_D IN (' + @Cols_For_Pivot_ + ')) AS P'
