如何使用C＃生成mdx查询？

Question

我是新来的mdx查询，我很好奇使用C＃的mdx查询生成，所以我搜索任何演示或开源，然后我发现Ranet.olap（https://ranetuilibraryolap.codeplex.com/）这是提供我所需要的。 服用dll之后，我尝试将它们合并到我的代码中。我正在粘贴我的完整的控制台代码，它应该会生成mdx查询，但它并没有这样做，我做错了什么？

     public static void startWork() 
     { 
      string connString = "Provider=MSOLAP.3; Data Source=localhost;Initial Catalog=AdventureWorkDW2008R2;Integrated Security=SSPI;"; 
      CubeDef cubes; 
      AdomdConnection conn = new AdomdConnection(connString); 
      conn.Open(); 
      cubes = conn.Cubes.Find("AdventureWorkCube");

Answer 1

仍然在修改代码，这台发动机的过程中，虽然你一些建议：

• 它看起来像你刚才抢立方体元数据（变暗，措施等），并把它传递给发电机。这听起来不像是生成MDX的方法。 MDX语句应该看起来像

  select 
  { 
      // measures, calculated members 
  } on 0, 
  { 
      // dimension data - sets 
  } on 1 // probably more axis 
  from **Cube** 
  

其他所有参数都是可选的

Answer 2

生成MDX查询（仅RANET OLAP 3.7版）的一个简单的例子：

using System.Collections.Generic; 
using Ranet.Olap.Core.Data; 
using Ranet.Olap.Core.Managers; 
using Ranet.Olap.Core.Types; 
using Ranet.Olap.Core.Wrappers; 

namespace ConsoleApplication1 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      startWork(); 
     } 

     public static void startWork() 
     { 

      var mdx = new QueryBuilderParameters 
      { 
       CubeName = "[Adventure Works]", 
       SubCube = "", 
       MdxDesignerSetting = new MDXDesignerSettingWrapper(), 
       CalculatedMembers = new List<CalcMemberInfo>(), 
       CalculatedNamedSets = new List<CalculatedNamedSetInfo>(), 
       AreaWrappersFilter = new List<AreaItemWrapper>(), 
       AreaWrappersColumns = new List<AreaItemWrapper>(), 
       AreaWrappersRows = new List<AreaItemWrapper>(), 
       AreaWrappersData = new List<AreaItemWrapper>() 
      }; 

      //define parameters 
      mdx.MdxDesignerSetting.HideEmptyColumns = false; 
      mdx.MdxDesignerSetting.HideEmptyRows = false; 
      mdx.MdxDesignerSetting.UseVisualTotals = false; 
      mdx.MdxDesignerSetting.SubsetCount = 0; 

      var itemCol1 = new Hierarchy_AreaItemWrapper 
      { 
       AreaItemType = AreaItemWrapperType.Hierarchy_AreaItemWrapper, 
       UniqueName = "[Customer].[Customer Geography]" 
      }; 
      mdx.AreaWrappersColumns.Add(itemCol1); 

      var itemRow1 = new Hierarchy_AreaItemWrapper 
      { 
       AreaItemType = AreaItemWrapperType.Hierarchy_AreaItemWrapper, 
       UniqueName = "[Date].[Calendar]" 
      }; 
      mdx.AreaWrappersRows.Add(itemRow1); 

      var itemData1 = new Measure_AreaItemWrapper(); 
      itemData1.AreaItemType = AreaItemWrapperType.Measure_AreaItemWrapper; 
      itemData1.UniqueName = "[Measures].[Internet Order Count]"; 
      mdx.AreaWrappersData.Add(itemData1); 

      string query = MdxQueryBuilder.Default.BuildQuery(mdx, null); 

     } 
    } 
} 

MDX查询结果：

SELECT 
HIERARCHIZE(HIERARCHIZE([Customer].[Customer Geography].Levels(0).Members)) DIMENSION PROPERTIES PARENT_UNIQUE_NAME, HIERARCHY_UNIQUE_NAME, CUSTOM_ROLLUP, UNARY_OPERATOR, KEY0 ON 0, 
HIERARCHIZE(HIERARCHIZE([Date].[Calendar].Levels(0).Members)) DIMENSION PROPERTIES PARENT_UNIQUE_NAME, HIERARCHY_UNIQUE_NAME, CUSTOM_ROLLUP, UNARY_OPERATOR, KEY0 ON 1 
FROM 
[Adventure Works] 
WHERE ([Measures].[Internet Order Count]) 
CELL PROPERTIES BACK_COLOR, CELL_ORDINAL, FORE_COLOR, FONT_NAME, FONT_SIZE, FONT_FLAGS, FORMAT_STRING, VALUE, FORMATTED_VALUE, UPDATEABLE, ACTION_TYPE
