Valor de propiedad

El nombre de la fuente que contiene la instrucción DDL que se enviará al servidor de Servicios de Análisis.

Ejemplos

El siguiente ejemplo de código crea, configura y ejecuta un nuevo ASExecuteDDLTask que carga la instrucción DDL para ejecutarla desde una conexión de archivo. La muestra utiliza la Source propiedad.

using Microsoft.SqlServer.Dts.Runtime;  
using Microsoft.DataTransformationServices.Tasks.DTSProcessingTask;  

class Module1  
{  

  public static void Main()  
  {  

    Package pkg = new Package();  

    ConnectionManager asCM;  
    asCM = pkg.Connections.Add("MSOLAP100");  
    asCM.Name = "Analysis Services Connection Manager";  
    asCM.ConnectionString = "Data Source=<servername>;" +  
      "Initial Catalog=Adventure Works DW;Provider=MSOLAP;" +  
      "Integrated Security=SSPI;Impersonation Level=Impersonate;";  

    ConnectionManager cmdCM;  
    cmdCM = pkg.Connections.Add("FILE");  
    cmdCM.Name = "Command Source Connection Manager";  
    cmdCM.ConnectionString = "C:\\ddltest.txt";  

    Executable exe = pkg.Executables.Add("Microsoft.DataTransformationServices.Tasks.DTSProcessingTask.ASExecuteDDLTask, " +  
      "Microsoft.SqlServer.ASTasks, Version=10.0.0.0, " +  
      "Culture=neutral, PublicKeyToken=89845dcd8080cc91");  
    TaskHost thTask = (TaskHost) exe;  
    {  
      thTask.Properties("ConnectionName").SetValue(thTask, "Analysis Services Connection Manager");  
      thTask.Properties("SourceType").SetValue(thTask, DDLSourceType.FileConnection);  
      thTask.Properties("Source").SetValue(thTask, "Command Source Connection Manager");  
    }  

    DTSExecResult valResults = pkg.Validate(pkg.Connections, pkg.Variables, null, null);  

    if (valResults==DTSExecResult.Success)  
    {  
      pkg.Execute();  
    }  

  }  

}

Comentarios

Esta propiedad funciona con la SourceType propiedad. Si el tipo fuente es una variable y la variable es nula, la String devuelto está vacía. Si el tipo fuente es una conexión y hay un error al recuperar la conexión, la String devuelto está vacía.

La instrucción DDL consiste en una instrucción XML for Analysis (XMLA) que contiene el XMLA Create, Alter, o Delete comandos, en un formato similar al ejemplo que sigue:
