如何使用Nodejs sequelize在findById中编辑和更新MySQL中的特定字段数据？

npm install sequelize

const Sequelize = require('sequelize');

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

// 定义模型
const User = sequelize.define('user', {
  name: {
    type: Sequelize.STRING,
    allowNull: false
  },
  age: {
    type: Sequelize.INTEGER,
    allowNull: false
  },
  email: {
    type: Sequelize.STRING,
    allowNull: false
  }
});

// 编辑和更新特定字段数据
User.findById(1)
  .then(user => {
    if (user) {
      user.name = 'New Name';
      user.age = 25;
      user.email = 'newemail@example.com';
      return user.save();
    }
  })
  .then(updatedUser => {
    console.log('Updated user:', updatedUser.toJSON());
  })
  .catch(error => {
    console.error('Error:', error);
  });
