MDX查询.如何解决"IN"问题?在“哪里"部分 [英] MDX queries. How can to solve "IN" in "where" part

问题描述

我有sql查询，我需要在olap cube中执行此查询.

I have sql query and i need this query execute in olap cube .

select count(distinct mi.id) from  [MTD_DEV].[dbo].[MenuItemAttributes] as m
  inner join  [dbo].[MenuItemOlds] as  mi
  on mi.id = m.MenuItemId
  inner join [dbo].[RestaurantlistItems] as rl
  on rl.RestaurantId = mi.RestaurantId
  where  m.AttributeId = 31 and rl.RestaurantListId = 69 and mi.PeriodId = 99 and m.MenuItemId in (select MenuItemId from  [MTD_DEV].[dbo].[MenuItemAttributes] where AttributeId = 6

并且我有有效的mdx查询，并且我需要为该查询添加运算符'IN'或其他解决方案

and i have working mdx query and I need to add operator 'IN' or something another solution for this query

  SELECT CROSSJOIN( 
    {[Measures].[Menu Item Olds Count],[Measures].[Restaurantlist Items Count]},
    {[Periods].[Id].[99],[Periods].[Id].[93],[Periods].[Id].[75]}) ON COLUMNS,
    {[Menu Item Olds].[id]} ON ROWS
     FROM [MTD DEV]
     where (
     {[Restaurant Lists].[Id].[69]},
     {[Attributes].[Id].[6]} ,
     {[Attribute Categories].[Id].[5]} -- or can use the same parameter {[Attributes].[Id].[31]}
           )

对问题的其他注释 n

在ms sql中，我必须通过某些参数m.AttributeId = 31来切片MenuItemOlds 然后从结果中我必须再次对参数AttributeId = 6进行切片. 在Sql中，它看起来像这样:

In ms sql I have to slice MenuItemOlds by some parameter m.AttributeId = 31 annd then from result I have to slice again for parameter AttributeId = 6. In Sql it looks like this:

select count(distinct mi.id) from  [MTD_DEV].[dbo].[MenuItemAttributes] as m
  inner join  [dbo].[MenuItemOlds] as  mi on mi.id = m.MenuItemId
  where  m.AttributeId = 31 and m.MenuItemId in (select MenuItemId from  [MTD_DEV].[dbo].[MenuItemAttributes] where AttributeId = 6

我在OLAP Cube中遇到问题. 我如何解决这个问题:

I have problem in OLAP Cube. How I see to solve this problem :

1.我得到AttributeId = 31的所有数据

1.I get all data where AttributeId = 31

 SELECT CROSSJOIN( 
    {[Measures].[Menu Item Olds Count],[Measures].[Restaurantlist Items Count]},
    {[Periods].[Id].[99],[Periods].[Id].[93],[Periods].[Id].[75]}) ON COLUMNS,
    {[Menu Item Olds].[id]} ON ROWS
     FROM [MTD DEV]
     where ({[Attributes].[Id].[31]})

此操作的结果-所有餐饮菜单项

the result of this - all catering menu items

1. 此后，在此菜单项集合中，我需要找到所有菜单项，其中{[Attributes].[Id].[6]}(儿童菜单)

当我尝试执行此类查询时:

When i am trying to execute such query :

 SELECT CROSSJOIN( 
    {[Measures].[Menu Item Olds Count],[Measures].[Restaurantlist Items Count]},
    {[Periods].[Id].[99],[Periods].[Id].[93],[Periods].[Id].[75]}) ON COLUMNS,
    {[Menu Item Olds].[id]} ON ROWS
     FROM [MTD DEV]
     where (
     {[Attributes].[Id].[6]} ,
     {[Attributes].[Id].[31]}
           )

我得到result，其中我的菜单项带有AttributeId.[6] +具有attributeId的menuItem.[31] 例如:

I get result , in which i have Menu items with AttributeId.[6] + menuItem with attributeId.[31] for example:

具有AttributeId的菜单项数.[6] = 11000项

count of menu items with AttributeId.[6] = 11000 items

具有AttributeId的菜单项数.[31] = 724000项

count of menu items with AttributeId.[31] = 724000items

结果是724000 + 11000 = 735000，但我不需要它

and result is 724000+11000 = 735000 but i don`t need it

我需要找到所有带有AttributeId.[31]的项目，在此集合中，我需要找到带有AttributeId.[6]的项目. 正确的查询结果必须少于11000个项目

i need to find all items with AttributeId.[31], and in this collection i need to find items with AttributeId.[6] The right result of query must be less than 11000 items

推荐答案

带有intersect的NonEmpty是否可以替代?

SELECT 
    {
      [Measures].[Menu Item Olds Count]
     ,[Measures].[Restaurantlist Items Count]
    }
  * 
    {
      [Periods].[Id].[99]
     ,[Periods].[Id].[93]
     ,[Periods].[Id].[75]
    } ON COLUMNS
 ,Intersect
  (
    NonEmpty
    (
      [Menu Item Olds].[id].[id].MEMBERS
     ,(
        [Attributes].[Id].[31]
       ,{
          [Measures].[Menu Item Olds Count]
         ,[Measures].[Restaurantlist Items Count]
        }
      )
    )
   ,NonEmpty
    (
      [Menu Item Olds].[id].[id].MEMBERS
     ,(
        [Attributes].[Id].[6]
       ,{
          [Measures].[Menu Item Olds Count]
         ,[Measures].[Restaurantlist Items Count]
        }
      )
    )
  ) ON ROWS
FROM [MTD DEV];
