ASExecuteDDLTask.Source Propriété

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

Valeur de propriété

Le nom de la source contenant l’instruction DDL à envoyer au serveur des Services d’Analyse.

Exemples

L’exemple de code suivant crée, configure et exécute un nouveau ASExecuteDDLTask qui charge l’instruction DDL à exécuter depuis une connexion de fichiers. L’échantillon utilise cette Source propriété.

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, " +

      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)

Remarques

Cette propriété fonctionne avec la SourceType propriété. Si le type source est une variable, et que la variable est nulle, le String type retourné est vide. Si le type source est une connexion et qu’il y a une erreur pour récupérer la connexion, la String version retournée est vide.

L’instruction DDL consiste en une instruction XML for Analysis (XMLA) qui contient les commandes XMLA Create, Alter, ou Delete commandes, dans un format similaire à l’exemple suivant :
