mysql - Sequelize - 原始 :true and raw:false 有什么区别

Question

根据 doc
如果选项.raw

If set to true, field and virtual setters will be ignored

但是字段和虚拟 setter 的含义是什么？
我看过很多网站，但似乎没有关于 options.raw 的值时查询结果格式的示例。是真/假。
假设我有 users在 Sequelize 中创建的模型

const Sequelize = require('sequelize');
const DataTypes = Sequelize.DataTypes;
const db = require('../sequelize')

let users = db.define('users', {
    id: {
      type: DataTypes.UUID,
      defaultValue: DataTypes.UUIDV4,
      allowNull: false,
      primaryKey: true
    },
    email: {
        type: DataTypes.STRING,
        allowNull: false,
        unique: 'email'
    },
    password: {
      type: DataTypes.STRING,
    },
  },
  {
    hooks: {
      beforeCount(options) {
        options.raw = true;  // what would be the difference when I set it to false
      }
    }
  }
);
  
users.sync().then(() => {
console.log('user table created');
});

module.exports = users;

当我设置 options.raw 时会有什么不同假的？
有什么例子吗？

Doc

In its most basic form set will update a value stored in the underlying dataValues object. However, if a custom setter function is defined for the key, that function will be called instead. To bypass the setter, you can pass raw: true in the options object.

如果 raw 为真，则自定义 getter 和 setter 将被忽略。

require('sqlite3');
const { Sequelize, DataTypes } = require('sequelize');

const sequelize = new Sequelize('sqlite::memory:')

const User = sequelize.define('User', {
  firstName: {
    type: DataTypes.STRING,
    get() {
        return this.getDataValue('firstName').toUpperCase()
    }
  },
  lastName: {
    type: DataTypes.STRING,
    set(value) {
        this.setDataValue('lastName', value + '--------');
    }
  }
});

let user = User.build({ firstName: 'John', lastName: 'Doe' });
console.log(user.lastName); // Doe--------
console.log(user.get()) // {firstName: "JOHN", id: null, lastName: "Doe--------"}

user = User.build({ firstName: 'John', lastName: 'Doe' }, {raw: true});
console.log(user.lastName); // Doe
console.log(user.get({raw: true})) // {firstName: "John", id: null, lastName: "Doe"}
