我如何显示所有"Price“与"amountt”相加的数据？

// 导入MySQL模块
const mysql = require('mysql');

// 创建数据库连接
const connection = mysql.createConnection({
  host: 'localhost',
  user: 'your_username',
  password: 'your_password',
  database: 'your_database'
});

// 连接数据库
connection.connect();

// 查询数据集
const query = 'SELECT Price, amountt FROM your_table';
connection.query(query, (error, results) => {
  if (error) throw error;

  let sum = 0;
  for (let i = 0; i < results.length; i++) {
    const record = results[i];
    const price = record.Price;
    const amount = record.amountt;
    sum += price + amount;
  }

  console.log('Total sum:', sum);
});

// 关闭数据库连接
connection.end();
