MDX 按维度排序

Question

在 SQL 端，我的数据是这样的：

Select f.id, f.TimeKey,t.CalendarYearMonth 
from FactSubmission f
inner join DimTime t on t.TimeKey = f.TimeKey
order by f.Id asc

从 MDX 排序我们有降序

SELECT
NON EMPTY ORDER(
 [DimTime.CalendarYearMonth].[CalendarYearMonth].Members,
 [DimTime.CalendarYearMonth].CurrentMember.Properties("MEMBER_KEY"), 
 DESC
 )  ON COLUMNS
FROM [PSE_FactSubmission]

上升

1 月日期不在这两种排序的顶部，这表明我按 FactSubmission.ID 键而不是 DimTime.CalendarYearMonth 进行排序

事情是这样运作的吗？我想把 1 月、2 月、3 月拉回来。

DimTime.CalendarYearMonthNum 是一列，其数据格式为 201501,201502,201503 等。这里尝试使用此列对 CalendarYearMonth 数据进行排序。

调试查询以选择键

非空查询

Answer 1

尝试使用不同的属性进行排序：

SELECT
NON EMPTY ORDER(
 [DimTime.CalendarYearMonth].[CalendarYearMonth].Members,
 [DimTime.CalendarYearMonth].CurrentMember.Properties("MEMBER_Value"), 
 DESC
 )  ON COLUMNS
FROM [PSE_FactSubmission];

或者这个：

SELECT
NON EMPTY ORDER(
 [DimTime.CalendarYearMonth].[CalendarYearMonth].Members,
 [DimTime.CalendarYearMonth].CurrentMember.MEMBERValue, 
 DESC
 )  ON COLUMNS
FROM [PSE_FactSubmission];

在上面你应该很好地使用DESC - 有时你需要通过添加B 即BDESC 来打破底层的层次顺序

从这里我看不到MEMBER_VALUE：http://mondrian.pentaho.com/documentation/mdx.php

...但是有一个函数.VALUE 所以不妨试试以下方法：

SELECT
NON EMPTY ORDER(
 [DimTime.CalendarYearMonth].[CalendarYearMonth].Members,
 [DimTime.CalendarYearMonth].CurrentMember.Value, 
 DESC
 )  ON COLUMNS
FROM [PSE_FactSubmission];

奇怪的是钥匙不起作用。如果你运行这样的东西，你会得到什么值？

WITH MEMBER [KEYcheck] AS
    [DimTime.CalendarYearMonth].CurrentMember.Properties("MEMBER_KEY")
    //[DimTime.CalendarYearMonth].CurrentMember.MEMBER_KEY
    //[DimTime.CalendarYearMonth].[CalendarYearMonth].CurrentMember.MEMBER_KEY
    //[DimTime].CurrentMember.MEMBER_KEY
SELECT
  [KEYcheck] ON 0,
  [DimTime.CalendarYearMonth].[CalendarYearMonth].Members ON 1
FROM [PSE_FactSubmission];

您正在按字母顺序排序。 February->January->March.

为了根据月份数进行排序，需要有一个映射一月 1 日、二月 2 日、三月 3 日的字段。

如果您在多维数据集中有这样的列，请使用它来进行排序。如果不创建如下所示的计算成员 -

WITH MEMBER Measures.CalendarMonth AS
CASE [DimTime.CalendarYearMonth].CurrentMember
 WHEN  [DimTime.CalendarYearMonth].&[January] THEN 1
 WHEN  [DimTime.CalendarYearMonth].&[February] THEN 2
 WHEN  [DimTime.CalendarYearMonth].&[March] THEN 3
END

SELECT
NON EMPTY ORDER(
 [DimTime.CalendarYearMonth].[CalendarYearMonth].Members,
 Measures.CalendarMonth, 
 DESC
 )  ON COLUMNS
FROM [PSE_FactSubmission]

为安德鲁编辑

with member Measures.[MonthNum] as
NonEmpty
    ( 
     [DimTime.CalendarYearMonthNum].[CalendarMonthNum].members,
     ([DimTime.CalendarYearMonth].[CalendarYearMonth].currentmember, Measures.foo)
    ).item(0).membervalue

select
non empty
order
  (
   [DimTime.CalendarYearMonth].[CalendarYearMonth].members,
   Measures.[MonthNum],
   desc
  ) on rows
from [PSE_FactSubmission]

编辑 - EXISTS

with member Measures.[MonthNum] as
EXISTS
      (
       [DimTime.CalendarYearMonthNum].[CalendarMonthNum].members,
       [DimTime.CalendarYearMonth].[CalendarYearMonth].currentmember,
       "SomeMeasureGroup"
      ).item(0).membervalue
