MDX 查询层次结构的前 10

Question

我无法编写 MDX 查询来获取具有层次结构的前 10 个城市。国家和城市的层次结构很简单。

我的结果应该是：

+---------+------------+--------+
| Country |    City    | Amount |
+---------+------------+--------+
| USA     | New York   |    123 |
| Germany | Berlin     |     65 |
| USA     | California |     58 |
| Germany | Munich     |     48 |
| Spain   | Barcelona  |     47 |
| France  | Paris      |     42 |
| Britain | London     |     36 |
| Russia  | Moskow     |     30 |
| Czech   | Prague     |     18 |
| Spain   | Madrid     |     17 |
+---------+------------+--------+

但我明白了：

+---------+------------+--------+
| Country |    City    | Amount |
+---------+------------+--------+
| USA     | New York   |    123 |
| Germany | Berlin     |     65 |
| USA     | California |     58 |
| Germany | Munich     |     48 |
| Spain   | Barcelona  |     47 |
+---------+------------+--------+

MDX 查询：

WITH
SET [~ROWS] AS
    TopCount(Hierarchize({{[Site].[Country].Members}, {[Site].[City].Members}}), 10, [Measures].[Amount])
SELECT
NON EMPTY {[Measures].[Amount]} ON COLUMNS,
NON EMPTY [~ROWS] ON ROWS
FROM [My_Cube]

当然，我知道 Hierarchize({{[Site].[Country].Members}, {[Site].[City].Members}}) 返回一组元组，但我不知道，什么是查询应该是什么？

Answer 1

试试这个，我用的是冒险作品

select {[Measures].[Reseller Order Count]
} on columns,
topcount
(
([Geography].[Country].[Country],[Geography].[City].[City])
,10,[Measures].[Reseller Order Count]
)

on rows 
from [Adventure Works]
