ResultSet 与 RowSet：选择哪一个以及何时选择

ResultSet和RowSet的选择与使用

java
try {
    // 创建数据库连接
    Connection connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/mydatabase", "username", "password");
    // 创建查询语句
    String sql = "SELECT * FROM users";
    Statement statement = connection.createStatement();
    // 执行查询并获取结果集
    ResultSet resultSet = statement.executeQuery(sql);
    // 遍历结果集并输出每一行数据
    while (resultSet.next()) {
        int id = resultSet.getInt("id");
        String name = resultSet.getString("name");
        int age = resultSet.getInt("age");
        System.out.println("ID: " + id + ", Name: " + name + ", Age: " + age);
    }
    // 关闭连接和结果集
    resultSet.close();
    statement.close();
    connection.close();
} catch (SQLException e) {
    e.printStackTrace();
}

java
try {
    // 创建RowSet对象
    JdbcRowSet rowSet = RowSetProvider.newFactory().createJdbcRowSet();
    // 配置RowSet的连接属性
    rowSet.setUrl("jdbc:mysql://localhost:3306/mydatabase");
    rowSet.setUsername("username");
    rowSet.setPassword("password");
    // 设置查询语句
    rowSet.setCommand("SELECT * FROM users");
    // 执行查询并获取结果集
    rowSet.execute();
    // 遍历结果集并输出每一行数据
    while (rowSet.next()) {
        int id = rowSet.getInt("id");
        String name = rowSet.getString("name");
        int age = rowSet.getInt("age");
        System.out.println("ID: " + id + ", Name: " + name + ", Age: " + age);
    }
    // 关闭RowSet
    rowSet.close();
} catch (SQLException e) {
    e.printStackTrace();
