慢MDX查詢

Question

我有一個查詢，它使用傳遞給查詢的參數爲當前月份&年建立一個月迄今和今年的SSRS報告。問題在於，由於有太多的客戶，零件號碼等，查詢花費的時間太長而無法執行。有什麼方法可以更好地編寫查詢或加快速度。對不起，我對此很新。下面是查詢...

Answer 1

我會忍不住去嘗試了以下各點出你的WHERE條款：

StrToMember 
    (
     [Measures].[Today string],constrained 
    ) 

所以WITH條款便可設爲如下所示：

WITH 
    MEMBER [Measures].[Key for Today] AS 
    Format 
    (
     Now(),'yyyyMMdd' 
    ) 
    MEMBER [Measures].[Today string] AS 
    '[Date].[Dates].[Day].&[' + [Measures].[Key for Today] + ']' 
    SET [today] AS 
    StrToSet([Measures].[Today string],constrained) 
    MEMBER [Measures].[Quantity Shipped MTD] AS 
    Sum 
    (
     MTD([today].ITEM(0)) 
    ,[Measures].[Quantity Shipped] 
    ) 
    MEMBER [Measures].[Quantity Shipped YTD] AS 
    Sum 
    (
     YTD([today].ITEM(0)) 
    ,[Measures].[Quantity Shipped] 
    ) 
    ... 
    ...
