Question

如何从以下MDX获得额外的总行数输出：

SELECT 
  {
    [Measures].[Internet Sales Amount]
   ,[Measures].[Internet Gross Profit]
   ,[Measures].[Sales Amount]
  } ON COLUMNS
 ,NON EMPTY 
    {[Customer].[City].[City] * [Product].[Product].[Product]} ON ROWS
FROM [Adventure Works]
WHERE 
  (
    [Date].[Fiscal Weeks].[Fiscal Year].&[2007]
   ,[Employee].[Employee Department].[Employee].&[105]
  );

因为我可以从纯SQL中获得。这是SQL聚合模拟

select 
    [Customer].[City].[City],[Product].[Product].[Product]
    , sum([Measures].[Internet Sales Amount]) as [Measures].[Internet Sales Amount]
    , sum([Measures].[Internet Gross Profit]) as [Measures].[Internet Gross Profit]
    , sum([Measures].[Sales Amount]) as [Measures].[Sales Amount]
from  [Adventure Works]
where   [Date].[Fiscal Weeks].[Fiscal Year].&[2007] and [Employee].[Employee Department].[Employee].&[105] 
group by [Customer].[City].[City],[Product].[Product].[Product]

union 

select 
    'Total'  ,null 
    , sum([Measures].[Internet Sales Amount]) as [Measures].[Internet Sales Amount]
    , sum([Measures].[Internet Gross Profit]) as [Measures].[Internet Gross Profit]
    , sum([Measures].[Sales Amount]) as [Measures].[Sales Amount]
from  [Adventure Works]
where   [Date].[Fiscal Weeks].[Fiscal Year].&[2007] and [Employee].[Employee Department].[Employee].&[105]

Answer 1

您是否需要额外的单个所有成员输出？

Select 
{
    [Measures].[Internet Sales Amount],
    [Measures].[Internet Gross Profit],
    [Measures].[Sales Amount]
} on 0,
{
    [Customer].[City].[All] *
    [Product].[Product].[All]
    +
    NonEmptyCrossJoin( 
        [Customer].[City].[City].Members,
        [Product].[Product].[Product].Members,
        2
    ) 
} on 1
From [Adventure Works]
Where 
(
    [Date].[Fiscal Weeks].[Fiscal Year].&[2007],
    [Employee].[Employee Department].[Employee].&[105]
)

顺便说一句，有advanced grouping within MS SQL server。您也可以发现this article对于理解MDX交叉连接很有用。

Answer 2

Danylo的回答可能不是一个完美的方法：

错误。他使用以下内容：[Customer].[City].[All] * [Product].[Product].[All]尝试交叉加入成员，但他需要明确地创建这些单个成员集：{[Customer].[City].[All]} * {[Product].[Product].[All]}
从我所阅读的内容NonEmptyCrossJoin是过去的遗留物，最好避免：http://sqlblog.com/blogs/mosha/archive/2006/10/09/mdx-nonempty-exists-and-evil-nonemptycrossjoin.aspx
如果我在1中详细说明了修正，那么脚本只返回1行，我认为这不是必需的？

我只是使用像这样的所有成员添加一个元组：

SELECT 
  {
    [Measures].[Internet Sales Amount]
   ,[Measures].[Internet Gross Profit]
   ,[Measures].[Sales Amount]
  } ON COLUMNS
 ,NON EMPTY 
    {
      (
        [Customer].[City].[All]
       ,[Product].[Product].[All]
      )
     ,{[Customer].[City].[City] * [Product].[Product].[Product]}
    } ON ROWS
FROM [Adventure Works]
WHERE 
  (
    [Date].[Fiscal Weeks].[Fiscal Year].&[2007]
   ,[Employee].[Employee Department].[Employee].&[105]
  );

额外的总行输出MDX
