Methoden

  Name Beschreibung
Öffentliche Methode CanUpdate *** Member deprecated; see Remarks. ***    A Boolean that indicates whether the new package XML can update the old package XML. (Geerbt von Task.)

Öffentliche Methode Execute Infrastruktur Executes the analysis services task. (Geerbt von ASTaskBase.)
Geschützte Methode Finalize (Geerbt von Object.)
Geschützte Methode FireError(String, String) Infrastruktur Raises an event when an error occurs. (Geerbt von ASTaskBase.)
Geschützte Methode FireError(Int32, String, String, String) Infrastruktur Raises an event when an error occurs. (Geerbt von ASTaskBase.)
Öffentliche Methode GetConnectionID Gets a String containing the ID of the connection. (Geerbt von Task.)
Öffentliche Methode GetConnectionName Gets a String containing the name of the connection. (Geerbt von Task.)
Öffentliche Methode GetHashCode Returns the hash code for this instance. (Geerbt von DtsObject.)
Öffentliche Methode GetType (Geerbt von Object.)

Beispiele

The following code sample creates, configures, and executes a new ASExecuteDDLTask that loads the DDL statement to execute from a file connection.

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");

      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)
    {
