重命名查询中的值

我在mySQL数据库中重命名列中的特定值时遇到问题。起初,我以为可以使用“AS”来重命名,但实际上我正在尝试重命名列中的值。我的专栏名为FoundLost。在此列中,我存储值“0”和“1”找到“0”,而“1”丢失。

我需要重命名此值的原因是因为我使用此数据库中的数据来创建pieChart。具有该功能。getName它提供名称“0”和“1”。

我希望有人能帮我!

带有查询的类的代码如下:

public static ObservableList getPChartFoundLost() {
    String query = "SELECT FoundLost, concat(round(count(FoundLost) *100 / (SELECT count(FoundLost) FROM Luggage))) AS percent FROM Luggage GROUP BY FoundLost";

    ObservableList FoundLost = FXCollections.observableArrayList();

    Connection connection = DatabaseUtils.connect();

    if (connection != null) {
        try {
            Statement statement = connection.createStatement();
            ResultSet resultSet = statement.executeQuery(query);

            while (resultSet.next()) {

                FoundLost.add(new PieChart.Data(resultSet.getString("FoundLost"), resultSet.getInt("percent")));
            }

            resultSet.close();
            statement.close();
        } catch (SQLException sqle) {
            System.out.println(sqle.getMessage());
        }
        DatabaseUtils.disconnect(connection);
    }

    return FoundLost;
}

控制器:

    public void clickPChartFoundLost(ActionEvent event) {

    //PieChart
    ObservableList FoundLost = StatisticsUtils.getPChartFoundLost();

    pieChart.setVisible(true);
    pieChart.setData(FoundLost);
    pieChart.setTitle("Found and Lost luggage");

    for (final PieChart.Data data : pieChart.getData()) {
        data.getNode().addEventHandler(MouseEvent.ANY,
                new EventHandler<MouseEvent>() {

            @Override
            public void handle(MouseEvent e) {

                //Label vullen met data van Observable list uit Database
                pieChartValueLable.setText(String.valueOf(data.getName()) + ": "
                        + String.valueOf(data.getPieValue()) + "%");
            }
        });
    }
}

谢谢
