ASExecuteDDLTask.Source Proprietà

public:
 property System::String ^ Source { System::String ^ get(); void set(System::String ^ value); };

public string Source { get; set; }

member this.Source : string with get, set

Public Property Source As String

Valore della proprietà

Il nome della sorgente che contiene l'istruzione DDL da inviare al server Analysis Services.

Esempio

Il seguente esempio di codice crea, configura ed esegue un nuovo ASExecuteDDLTask che carica l'istruzione DDL da eseguire da una connessione a un file. Il campione utilizza questa Source proprietà.

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();  
    }  

  }  

}

Commenti

Questa proprietà funziona con la SourceType proprietà. Se il tipo sorgente è una variabile e la variabile è nulla, la String restituita è vuota. Se il tipo di sorgente è una connessione e c'è un errore nel recuperare la connessione, il String ritorno è vuoto.

L'istruzione DDL consiste in un'istruzione XML for Analysis (XMLA) che contiene i comandi XMLA Create, Alter, Delete o comandi, in un formato simile all'esempio che segue:
