How to fill up a TableView with database data

Question

I\'ve been trying to load a TableView with data queried from a database, but can\'t seem to get it to work.

This is my first attempt at trying to fill up a database

Answer 1

public TableView queryToTable(String sql) {
    TableView result = new TableView();
    ObservableList data = FXCollections.observableArrayList();

    jdbcTemplate.query(sql, (rs)->{
        for(int i=0 ; i,ObservableValue>(){
                public ObservableValue call(TableColumn.CellDataFeatures param) {
                    return new SimpleStringProperty(param.getValue().get(j).toString());
                }
            });
            result.getColumns().addAll(col);
        }

        while(rs.next()){
            ObservableList row = FXCollections.observableArrayList();
            for(int i=1 ; i<=rs.getMetaData().getColumnCount(); i++)
                row.add(rs.getString(i));
            data.add(row);
        }
        return null;
    });
    return result;
}
