      OracleCommand myCommand = new OracleCommand();
      myCommand.Connection = myConnection;
      myConnection.BeginTransaction();
      try
      {
        myCommand.CommandText = "INSERT INTO Test.Dept(DeptNo, DName) Values(50, 'DEVELOPMENT')";
        myCommand.ExecuteNonQuery();
        myCommand.CommandText = "INSERT INTO Test.Dept(DeptNo, DName) Values(60, 'PRODUCTION')";
        myCommand.ExecuteNonQuery();
        myConnection.Commit();
        Console.WriteLine("Both records are written to database.");
      }
      catch(Exception e)
      {
        myConnection.Rollback();
        Console.WriteLine(e.ToString());
        Console.WriteLine("Neither record was written to database.");
      }
      finally
      {
        myConnection.Close();
      }
    }
    Public Sub RunOracleTransaction(myConnString As String)
      Dim myConnection As New OracleConnection(myConnString)
      myConnection.Open()
      Dim myCommand As New OracleCommand()
      myCommand.Connection = myConnection
      myConnection.BeginTransaction()
      Try
        myCommand.CommandText = "INSERT INTO Test.Dept(DeptNo, DName) Values(50, 'DEVELOPMENT')"
        myCommand.ExecuteNonQuery()

      Catch e As Exception
        myConnection.Rollback()
        Console.WriteLine(e.ToString())
