MDX 按日期过滤结果

Question

我想过滤我的查询结果，因此它 return 仅当日期大于指定日期时才显示值。

我写了类似的东西：

SELECT { [Measures].[Net sales] } ON COLUMNS
    FROM [Sales]
    WHERE ( { [Department].[Department name].&[WRO], [Department].[Department name].&[KAT]},
            {( FILTER([Time].[Date], [Date].CURRENTMEMBER.MEMBER_KEY >= '2015-10-10'))} );

但它 return 为空。没有这部分 filter() 它 return 是整个 [Net sales]。

Answer 1

试试这个：

SELECT { [Measures].[Net sales] } ON COLUMNS
FROM [Sales]
WHERE ( { [Department].[Department name].&[WRO], [Department].[Department name].&[KAT]},
       {( FILTER([Time].[Date], [Date].CURRENTMEMBER.MEMBER_KEY > '2015-10-10'))} );

Answer 2

也许是这样的：

WITH 
MEMBER [Measures].[Net sales NEW] AS 
   SUM(
     FILTER(
      [Time].[Date].[Date].MEMBERS, 
      [Time].[Date].CURRENTMEMBER.MEMBER_KEY 
          >= 20151010
     )
     , [Measures].[Net sales]
   )
SELECT 
      {
       [Measures].[Net sales]
      ,[Measures].[Net sales NEW] 
      } ON 0
FROM  [Sales]
WHERE {
       [Department].[Department name].&[WRO]
     , [Department].[Department name].&[KAT]
       };

另一种方法：

WITH 
MEMBER [Measures].[Date_key] AS 
      [Time].[Date].CURRENTMEMBER.MEMBER_KEY 
MEMBER [Measures].[Net sales NEW] AS 
   SUM(
      [Time].[Date].[Date].MEMBERS, 
      IIF(
         [Measures].[Date_key] >= 20151010
       , [Measures].[Net sales]
       , NULL
      )
   )
SELECT 
      {
       [Measures].[Net sales]
      ,[Measures].[Net sales NEW] 
      } ON 0
FROM  [Sales]
WHERE {
       [Department].[Department name].&[WRO]
     , [Department].[Department name].&[KAT]
       };

一个问题：这绝对是你的日期键的格式吗？ '2015-10-10'

根据 WHERE 切片器检查密钥的一种可能的可视化方法是使用如下更简单的脚本：

WITH 
MEMBER [Measures].[Date_key] AS 
      [Time].[Date].CURRENTMEMBER.MEMBER_KEY 
SELECT 
      [Measures].[Date_key] ON 0
      [Time].[Date].[Date].MEMBERS ON 1
FROM  [Sales]
WHERE {
       [Department].[Department name].&[WRO]
     , [Department].[Department name].&[KAT]
      };

不确定以上内容有什么问题 - 我明天需要针对 AdvWrks 多维数据集进行测试。

另一种方法可能是：

SELECT 
      [Measures].[Net sales] } ON 0
FROM  [Sales]
WHERE ( 
         { [Department].[Department name].&[WRO]
         , [Department].[Department name].&[KAT] }
         , {[Time].[Date].[Date].&[10 Oct 2015]:null} 
      );

注意：您需要将 10 Oct 2015 更改为多维数据集中的格式，并且 10 Oct 2015 必须是多维数据集中存在的日期。
