如何在每一行上乘以2列，并使用Sequelize对所有结果求和？

const { Sequelize, DataTypes } = require('sequelize');

// 创建Sequelize实例
const sequelize = new Sequelize('database', 'username', 'password', {
  host: 'localhost',
  dialect: 'mysql',
});

// 定义数据模型
const Number = sequelize.define('Number', {
  value: {
    type: DataTypes.INTEGER,
    allowNull: false,
  },
});

Number.sum('value', { where: {}, attributes: [[sequelize.literal('SUM(value * 2)'), 'sum']] })
  .then(result => {
    console.log('Sum:', result.sum);
  })
  .catch(error => {
    console.error('Error:', error);
  });
