如何为每一行更新不同的值？

import java.sql.*;

public class UpdateRowsExample {
    public static void main(String[] args) {
        String url = "jdbc:mysql://localhost:3306/mydatabase";
        String username = "root";
        String password = "password";

        try {
            // 连接到数据库
            Connection connection = DriverManager.getConnection(url, username, password);

            // 选择要更新的行
            String selectQuery = "SELECT id, name FROM mytable WHERE condition = 'some condition'";
            Statement selectStatement = connection.createStatement();
            ResultSet resultSet = selectStatement.executeQuery(selectQuery);

            // 更新每一行的值
            while (resultSet.next()) {
                int id = resultSet.getInt("id");
                String name = resultSet.getString("name");

                // 根据需要更新每一行的值
                String updatedName = name + "_updated";

                // 更新行的值
                String updateQuery = "UPDATE mytable SET name = ? WHERE id = ?";
                PreparedStatement updateStatement = connection.prepareStatement(updateQuery);
                updateStatement.setString(1, updatedName);
                updateStatement.setInt(2, id);
                updateStatement.executeUpdate();
            }

            // 关闭连接
            resultSet.close();
            selectStatement.close();
            connection.close();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}
