Метаданные метаданных SSAS с использованием компонента сценария SSIS с программой C#

Question

Я использую компонент сценария в ssis с кодом C#, используя пространство имен Microsoft.Analysisservices для извлечения метаданных куба. Код выглядит как этот

using System; 
using System.Data; 
using Microsoft.SqlServer.Dts.Pipeline.Wrapper; 
using Microsoft.SqlServer.Dts.Runtime.Wrapper; 
using Microsoft.AnalysisServices; 
using System.Windows.Forms; 

[Microsoft.SqlServer.Dts.Pipeline.SSISScriptComponentEntryPointAttribute] 
public class ScriptMain : UserComponent 
{ 

//IDTSConnectionManager100 connMgr; 
Server OLAPServer = new Server();  

public override void AcquireConnections(object Transaction) 
{ 
    OLAPServer.Connect(this.Connections.OLAPConnection.ConnectionString); 
} 


public override void PreExecute() 
{ 
    base.PreExecute(); 
    /* 
     Add your code here for preprocessing or remove if not needed 
    */ 
} 

public override void PostExecute() 
{ 
    base.PostExecute(); 
    /* 
     Add your code here for postprocessing or remove if not needed 
     You can set read/write variables here, for example: 
     Variables.MyIntVar = 100 
    */ 
} 

public override void CreateNewOutputRows() 
{ 
    IDTSVariables100 vars = null; 
    string OLAPDBName; 
    VariableDispenser.LockOneForRead("OLAPDBName", ref vars); 
    Database OLAPDB; 

    OLAPDBName = vars[0].Value.ToString(); 
    try 
    { 
     OLAPDB = OLAPServer.Databases.GetByName(OLAPDBName); 
    } 
    catch 
    { 
     return; 
    } 

    // loop through cubes 
     CubeCollection Cubes = OLAPDB.Cubes; 
     MeasureGroupCollection Mgroups;

     foreach (Cube cb in Cubes) 
     { 
     //Test for one Measure Group 
     //MeasureGroup mgroup = Mgroups.GetByName("Inward Exposure"); 

      Mgroups = cb.MeasureGroups; 
     // all dimensions associated with that Measure Group 

      // loop through Measure Groups 
      foreach (MeasureGroup mg in Mgroups) 
      { 
       // loop though all cube dimensions 
       Dimensions = cb.Dimensions;**strong text** 
       foreach (CubeDimension dim in Dimensions) 
       { 
        bool CanBeAnalysed = false;**strong text** 
        // loop through dimensions and see if dimension exists in mgroupDims (ie check if it can be analysed) 

        MgroupDims = mg.Dimensions; 
        foreach (MeasureGroupDimension mgd in MgroupDims) 
        { 
         if (mgd.CubeDimension == dim) 
         { 
          CanBeAnalysed = true; 

          break; 
         } 

        }

         // get every measure in measuregroup

          if (m.MeasureExpression != null)

          Output0Buffer.AddRow();

Я был успешным в получении метаданных кубы с выше code.However, я застрял на получение метаданных перспективного куба и отношений групп с мерой, то есть ли мера групп много. Любая помощь очень ценится.

Answer 1

Вот несколько кодов для определения отношений измерения, включая много-ко-многим. Смотрите функцию GetDimensionUsage: https://bidshelper.svn.codeplex.com/svn/SSAS/PrinterFriendlyDimensionUsage.cs

Вот код вокруг навигационных точек зрения: https://bidshelper.svn.codeplex.com/svn/SSAS/TriStatePerspectivesPlugin.cs

Начать чтение по следующей строке:

if (perspective.MeasureGroups.Contains(mg.Name))
