使用計算成員傳遞參數 - MDX

Question

我正在嘗試使用計算所得成員來創建帶參數的查詢。

我已經爲「硬編碼」的司法計數創建了計算成員，並且創建的參數不影響每個組的總計。

但是，我需要使用工作參數列出每個總計數。如果所選司法類型沒有價值，則應顯示零計數。

我確定有一個簡單的方法，但即時通訊相當新的MDX/SSRS。任何幫助是極大的讚賞！

下面是該查詢：

WITH 

Member [Measures].[Jud] as 
     (
     [Dim Foreclosure Loan].[Judicial Flag].[1], 
     [Dim Foreclosure Loan].[FCL Stage].&[Sale Held], 
     [Measures].[Loan Count] 
     ) 
Member [Measures].[Non-Jud] as 
     (
     [Dim Foreclosure Loan].[Judicial Flag].[0], 
     [Dim Foreclosure Loan].[FCL Stage].&[Sale Held], 
     [Measures].[Loan Count] 
     ) 
Member [Measures].[Total] as 
     (
     [Dim Foreclosure Loan].[Judicial Flag], 
     [Dim Foreclosure Loan].[FCL Stage].&[Sale Held], 
     [Measures].[Loan Count] 
     ) 
-------------------------------- Query Begins -------------------------------- 
SELECT NON EMPTY 
     { 
     ([Dim Date].[Calendar].[Day].Members) 
     } ON ROWS, 
     NON EMPTY 
     ({ 
     ([Measures].[Jud]), 
     ([Measures].[Non-Jud]), 
     ([Measures].[Total]) 
     }) ON COLUMNS 
     FROM (SELECT (STRTOSET(@DimForeclosureLoanJudicialFlag, CONSTRAINED)) ON COLUMNS 
     FROM [Foreclosure]) 
     WHERE 
     (IIF(STRTOSET(@DimForeclosureLoanJudicialFlag, CONSTRAINED).Count = 1, 
     STRTOSET(@DimForeclosureLoanJudicialFlag, CONSTRAINED), 
     [Dim Foreclosure Loan].[Judicial Flag].currentmember) 
     )CELL PROPERTIES VALUE 

更新：所提供的IIF statment需要幫助;見下面的評論。

Answer 1

我不是100％清楚你問什麼，但如果我要重申它，我認爲這是你想要做的。我想你想在專欄上看到Jud，Non-Jud和Total。我想你正在嘗試使用這個參數來選擇一個特定的司法旗幟。不清楚的是，參數值是否限制爲1和2，如果您爲度量顯示的，或者是否存在1和2的子級別的層次結構，我將假設第一個，因爲它是最簡單的解釋，我們可以從那裏去。

您需要設置司法標誌1和2的措施以考慮WHERE條款中的內容。現在它們是硬編碼的，它告訴SSAS忽略WHERE條款中的任何內容。您需要通過在度量定義中包含IIF聲明來有條件地使用它。您應該返回一個NULL值作爲False條件，以便SSAS可以優化地執行查詢，然後使用format_string屬性填充0來代替NULL（這比在False條件下使用0來獲得更好的性能）。但是，您列上的NON EMPTY關鍵字將消除WHERE條款中未包含的司法旗幟，因此您需要刪除該旗幟。將它放在行上，以便只顯示具有Jud或Non-Jud值的日子。

這裏是基於我的你想要做什麼的猜測在查詢嘗試：

WITH 
    MEMBER [Measures].[Jud] AS 
    iif(
     [Dim Foreclosure Loan].[Judicial Flag].CurrentMember is 
      [Dim Foreclosure Loan].[Judicial Flag].[1], 
      (
       [Dim Foreclosure Loan].[Judicial Flag].[1] 
      ,[Dim Foreclosure Loan].[FCL Stage].&[Sale Held] 
      ,[Measures].[Loan Count] 
      ), 
      NULL), format_string="#;#;0;0" 
    MEMBER [Measures].[Non-Jud] AS 
    iif(
     [Dim Foreclosure Loan].[Judicial Flag].CurrentMember is 
      [Dim Foreclosure Loan].[Judicial Flag].[0], 
      (
       [Dim Foreclosure Loan].[Judicial Flag].[0] 
      ,[Dim Foreclosure Loan].[FCL Stage].&[Sale Held] 
      ,[Measures].[Loan Count] 
      ), 
      NULL), format_string="#;#;0;0" 
    MEMBER [Measures].[Total] AS 
    (
     [Dim Foreclosure Loan].[Judicial Flag] 
    ,[Dim Foreclosure Loan].[FCL Stage].&[Sale Held] 
    ,[Measures].[Loan Count] 
    ) 
SELECT 
    NON EMPTY 
    { 
     [Dim Date].[Calendar].[Day].MEMBERS 
    } ON ROWS 
, 
    { 
     [Measures].[Jud] 
    ,[Measures].[Non-Jud] 
    ,[Measures].[Total] 
    } ON COLUMNS

    IIF

    = 1
