如何在node js sequelize中编写此查询？

const Sequelize = require('sequelize');
const sequelize = new Sequelize('database', 'username', 'password', {
  host: 'localhost',
  dialect: 'mysql' // 或者其他数据库类型，如postgres、sqlite等
});

// 定义模型（如果有）
const User = sequelize.define('user', {
  firstName: {
    type: Sequelize.STRING,
    allowNull: false
  },
  lastName: {
    type: Sequelize.STRING,
    allowNull: false
  }
});

// 同步模型到数据库
sequelize.sync();

User.findAll().then(users => {
  console.log(users);
}).catch(err => {
  console.error('查询失败：', err);
});

User.findAll({
  where: {
    lastName: 'Smith'
  }
}).then(users => {
  console.log(users);
}).catch(err => {
  console.error('查询失败：', err);
});

const { Op } = Sequelize;

User.findAll({
  where: {
    [Op.and]: [
      { firstName: 'John' },
      { lastName: 'Smith' }
    ]
  }
}).then(users => {
  console.log(users);
}).catch(err => {
  console.error('查询失败：', err);
});
