10 차원의 MDX 쿼리로 SSAS 큐브 메모리가 폭발 함

Question

9 차원까지 매우 빠르고 효율적으로 실행되는 mdx 쿼리로 SSAS 큐브에 쿼리하고 있습니다. 일단 10 차원을 맞추면 큐브의 메모리 사용이 통제 불능 상태가되어 기본적으로 컴퓨터가 충돌 할 때까지 사용 가능한 모든 메모리를 사용합니다. 누구나 왜 10이 9와 근본적으로 다른가에 대한 대답을 할 수 있습니까?

Answer 1

하위 큐브 구문을 사용해 보셨습니까? 어쩌면 더 잘 작동 할 수도 있습니다 ...

Select 
    {...} On Columns, 
    {...} On Rows 
    from (Select {{[Response Wave].[Wave].&[20110101]}} On Columns 
      From { 
     [Question Answer Primary].[QUESTIONCATEGORY].&[AfricaSpecific], 
     [Question Answer Primary].[QUESTIONCATEGORY].&[ChinaSpecific], 
     ... 
     [Question Answer Primary].[QUESTIONCATEGORY].&[DistributionSupport], 
     [Question Answer Primary].[QUESTIONCATEGORY].&[AdvertisingSupport] 
    } On Columns FROM [SATPlus_Cube])) 
    WHERE .....
