MDX 计算的成员错误

Question

怎样才能做一个计算会员？我收到此错误Mondrian Error:Member expression 'Filter(Descendants([User].[User Name].Members), ([User].[User Name].CurrentMember.Properties("location") = 'foo')) 不能是集合

WITH MEMBER [Measures].[some users] AS
Filter(
  Descendants([User].[User Name].Members), 
  [User].[User Name].CurrentMember.Properties("location") = 'foo'
 )  
)

SELECT
 NON EMPTY {[Measures].[some users]} ON COLUMNS,
 NON EMPTY CrossJoin(
   [Date].[Date].Members, 
   [Customer].[Customer Name].Members
  ) ON ROWS

FROM [Users]

Answer 1

FILTER 返回一个SET，而您尝试在WITH 子句中将其分配给MEMBER。

这应该可以，但没有指定度量，因此您将获得默认度量：

SELECT
 NON EMPTY 
{Filter(
  Descendants([User].[User Name].Members), 
  [User].[User Name].CurrentMember.Properties("location") = 'foo'
 ) } 
ON COLUMNS,
 NON EMPTY CrossJoin(
   [Date].[Date].Members, 
   [Customer].[Customer Name].Members
  ) ON ROWS

FROM [Users];

您可以在WHERE 子句中决定一个措施：

SELECT
 NON EMPTY 
{Filter(
  Descendants([User].[User Name].Members), 
  [User].[User Name].CurrentMember.Properties("location") = 'foo'
 ) } 
ON COLUMNS,
 NON EMPTY CrossJoin(
   [Date].[Date].Members, 
   [Customer].[Customer Name].Members
  ) ON ROWS

FROM [Users]
WHERE [Measures].[aMeasureThatFitsContext];

使用RANK 的示例。只是有点不确定这是否适合您的原始脚本？

WITH 
  SET [myFilteredSet] AS 
    Filter(
      Descendants([User].[User Name].Members), 
      [User].[User Name].CurrentMember.Properties("location") = 'foo'
    )
  MEMBER [Measures].[userRank] AS
    RANK(
      [User].[User Name].CURRENTMEMBER,
      [myFilteredSet],
      [Measures].[EXISTING_MEASURE] //<<this is the measure you are ordering by  
    ) 
SELECT
 NON EMPTY 
   {[Measures].[EXISTING_MEASURE],[Measures].[userRank] } 
 ON COLUMNS,
 NON EMPTY 
   [myFilteredSet] 
 ON ROWS
FROM [Users]
