Exemplos

The following code sample creates, configures, and executes a new DTSProcessingTask that processes the Targeted Mailing mining model in the Adventure Works DW sample database.

    asCM.ConnectionString = "Data Source=<servername>;" +
      "Initial Catalog=Adventure Works DW;Provider=MSOLAP;" +
      "Integrated Security=SSPI;Impersonation Level=Impersonate;";
