Ejemplos

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");
    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();
    }

  }
