慢MDX查询

Question

我有一个查询，它构建了当月的SSRS报告的当月和年初至今;年使用传递给查询的参数。问题是因为有太多的客户，部件号等，查询执行时间太长。有没有办法更好地编写查询或加快查询速度。对不起，我对此非常陌生。以下是查询...

Answer 1

我很想尝试将以下内容移出WHERE条款：

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

因此WITH子句可能如下所示：

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]
    ) 
  ...
