MDX 쿼리 작성기 구현

Question

큐브를 쿼리하는 데 Microsoft.AnalysisServices.AdomdClient을 사용하고 있습니다. 내 큐브를 쿼리하기 위해 AdomdCommand 개체에 전달하는 다차원 식 (MDX) 쿼리가 있습니다. Measures, Dimensions, Levels 등의 목록을 전달하고 해당 MDX 쿼리의 문자열을 생성하는 데 사용할 수있는 MDX 빌더 클래스를 갖고 싶습니다.

이미 존재합니까? 를위한 좋은 시작이다

Answer 1

: 오픈 소스 코드는 당신을위한 대안이 http://www.c-sharpcorner.com/UploadFile/akrishnaraj/MdxQueryBuilder12052005041819AM/MdxQueryBuilder.aspx

경우,이 라이브러리는 MDX 생성기가 포함 포함 템플릿이 될 수 있습니다에 http://code.google.com/p/ranet-uilibrary-olap/

Answer 2

는 MDX 쿼리를 생성하려면 Ranet Olap을 사용했습니다. 다음은 간단한 예제 코드입니다. 필터 설정 및 여러 측정 값 사용과 같은 일반적인 사용 사례를 보여줍니다. 결과
