案例 MDX 中的多个语句

【中文标题】案例 MDX 中的多个语句

【英文标题】：Multiple statements in case MDX

【发布时间】：2016-04-15 11:40:50

【问题描述】：

我必须编写 MDX，它将显示在列上并将行分为三组。第一组以少数数字区分，第二组以属性区分，第三组是其余不适合的地方。

到目前为止，我的代码看起来像这样：

case 
    when [Customer].[Customer's Document].CURRENTMEMBER.MEMBERVALUE = "4254255527"  then "ABC"
    when [Customer].[Customer's Document].CURRENTMEMBER.MEMBERVALUE = "2752637520"  then "ABC"
    when [Customer].[Customer's Document].CURRENTMEMBER.MEMBERVALUE = "5637839739"  then "ABC"
    when [Customer].[Customer's Document].CURRENTMEMBER.MEMBERVALUE = "9378793737"  then "ABC"
    when [Customer].[Customer's Document].CURRENTMEMBER.MEMBERVALUE = "3789789397"  then "ABC"
    when [Document].[Document series].CURRENTMEMBER.MEMBERVALUE = "XYZ" then "XYZ"
    else "Rest"
end

但我每次都在“休息”。

我应该如何纠正？

编辑： 再次尝试但仍然无法正常工作：

case 
    when [Customer].[Customer's Document].[&5196189651]  then "ABC"
    when [Customer].[Customer's Document].[&7885181585]  then "ABC"
    when [Customer].[Customer's Document].[&7511535861]  then "ABC"
    when [Customer].[Customer's Document].[&4742575277]  then "ABC"
    when [Customer].[Customer's Document].[&7272727272]  then "ABC"
    when [Customer's Document].[Document Series].[&CHP] then "XYZ"
    else "Rest"
end

【问题讨论】：

客户文档的值、键和名称属性是什么？客户维度的结构是什么？您如何查询此度量并将“其余”视为您的最终结果？请将查询添加到您的问题中，以便我们提供帮助。

@Dodzik - 维度 [Customer] 在最终的 SELECT 子句的行上？！如果它不在行上，则 Currentmember 是 All 成员 ....currentmember 仅在维度实际上是 current 时起作用，即在上下文中。这可能是你一直休息的原因。你可以添加你的 mdx 脚本的其余部分吗？

【参考方案1】：

我感觉你想做一些类似以下的事情：

WITH 
  SET [ABC] AS 
    
      [Customer].[Customer's Document].&[5196189651]
     ,[Customer].[Customer's Document].&[7885181585]
     ,[Customer].[Customer's Document].&[7511535861]
     ,[Customer].[Customer's Document].&[4742575277]
     ,[Customer].[Customer's Document].&[7272727272]
     
  MEMBER [Customer].[All].[ABC] AS 
    Aggregate([ABC]) 
  MEMBER [Customer].[All].[XYZ] AS 
    [Customer].[Customer's Document].[Document Series].&[CHP] 
  SET [REST] AS 
    Except
    (
      [Customer].[Customer's Document].MEMBERS
     ,[ABC]
    ) 
  MEMBER [Customer].[All].[Rest] AS 
    Aggregate([REST]) 
  SET [FINAL] AS 
    
      [Customer].[All].[ABC]
     ,[Customer].[All].[XYZ]
     ,[Customer].[All].[Rest]
     
SELECT 
  [FINAL] ON 1
 ,[Measures].[Amount] ON 0
FROM [YourCube];

或者可能是以下内容：

WITH 
  SET [ABC] AS 
    
      [Customer].[Customer's Document].&[5196189651]
     ,[Customer].[Customer's Document].&[7885181585]
     ,[Customer].[Customer's Document].&[7511535861]
     ,[Customer].[Customer's Document].&[4742575277]
     ,[Customer].[Customer's Document].&[7272727272]
     
  MEMBER [Customer].[All].[ABC] AS 
    Aggregate([ABC]) 
  MEMBER [Customer].[All].[XYZ] AS 
    [Customer].[Customer's Document].[Document Series].&[CHP] 
  SET [REST] AS 
    Except
    (
      [Customer].[Customer's Document].MEMBERS
     ,
        [ABC]
       ,[Customer].[Customer's Document].[Document Series].&[CHP]
      
    ) 
  MEMBER [Customer].[All].[Rest] AS 
    Aggregate([REST]) 
  SET [FINAL] AS 
    
      [Customer].[All].[ABC]
     ,[Customer].[All].[XYZ]
     ,[Customer].[All].[Rest]
     
SELECT 
  [FINAL] ON 1
 ,[Measures].[Amount] ON 0
FROM [YourCube];

只是一个警告 - 在接受的答案中有以下mdx：

case 
    when [Customer].[Customer's Document].CURRENTMEMBER.MEMBERVALUE = "4254255527"  then "ABC"
    when [Customer].[Customer's Document].CURRENTMEMBER.MEMBERVALUE = "2752637520"  then "ABC"
    when [Customer].[Customer's Document].CURRENTMEMBER.MEMBERVALUE = "5637839739"  then "ABC"
...
...

这可能被标记为解决方案，但不是很好mdx。在这种情况下，应该使用IS 运算符：

case 
    when [Customer].[Customer's Document].CURRENTMEMBER IS 
             [Customer].[Customer's Document].[Customer's Document].&[4254255527]  then "ABC"
    when [Customer].[Customer's Document].CURRENTMEMBER IS 
             [Customer].[Customer's Document].[Customer's Document].&[2752637520]  then "ABC"
    when [Customer].[Customer's Document].CURRENTMEMBER IS 
             [Customer].[Customer's Document].[Customer's Document].&[5637839739]  then "ABC"
...
...

【讨论】：

您的意思是在括号外加“&”吗[客户].[客户文档].&[7272727272]

@Ala 我刚刚从原始问题中复制了成员名称，但是您是对的，& 通常在大括号之外。

@Dodzik - 我觉得这被错误地标记了，因为 Proffesore 的答案中的一般 mdx 不是很好 - 这样做 t].CURRENTMEMBER.MEMBERVALUE = "4254255527" 是使用 IS 运算符的一个糟糕的选择

【参考方案2】：

您使用的是哪种 BI 工具；您可以将此作为名称计算添加到数据源视图中的新列（右键单击客户表->新建命名计算->列名：XXX）。 示例：

CASE 
    WHEN ACOLUMN BETWEEN 0 AND 10 THEN 'ABC'
    WHEN ACOLUMN BETWEEN 10 AND 20 THEN 'ABC'
    ELSE 'REST'
END

我相信在这种情况下你必须使用相同的层次结构。或者你可以将你的代码分成两部分：

case 
    when [Customer].[Customer's Document].CURRENTMEMBER.MEMBERVALUE = "4254255527"  then "ABC"
    when [Customer].[Customer's Document].CURRENTMEMBER.MEMBERVALUE = "2752637520"  then "ABC"
    when [Customer].[Customer's Document].CURRENTMEMBER.MEMBERVALUE = "5637839739"  then "ABC"
    when [Customer].[Customer's Document].CURRENTMEMBER.MEMBERVALUE = "9378793737"  then "ABC"
    when [Customer].[Customer's Document].CURRENTMEMBER.MEMBERVALUE = "3789789397"  then "ABC"
    when [Document].[Document series].CURRENTMEMBER.MEMBERVALUE = "XYZ" then "XYZ"
    else "Rest"
end

CASE
when [Document].[Document series].CURRENTMEMBER.MEMBERVALUE = "XYZ" then "XYZ"
    else "Rest"
end
