在WHERE子句中使用多个变量的Java SQL Select语句

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;

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

        try (Connection conn = DriverManager.getConnection(url, username, password)) {
            String sql = "SELECT * FROM mytable WHERE column1 = ? AND column2 = ?";
            PreparedStatement statement = conn.prepareStatement(sql);
            statement.setString(1, "value1");
            statement.setString(2, "value2");

            ResultSet resultSet = statement.executeQuery();

            while (resultSet.next()) {
                // 处理查询结果
            }

        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}
