Sequelizejs，创建索引时如何对字段值进行排序

const { Model, DataTypes, Index } = require('sequelize');
const sequelize = new Sequelize('database', 'username', 'password', {
  dialect: 'mysql',
});

class User extends Model {}
User.init(
  {
    name: {
      type: DataTypes.STRING,
      allowNull: false,
    },
    age: {
      type: DataTypes.INTEGER,
      allowNull: false,
    },
  },
  {
    sequelize,
    modelName: 'User',
  }
);

// 使用@Index装饰器创建索引
@Index('name_age_index', ['name', 'age'], { order: 'ASC' })
class User extends Model {}

// 在options中定义索引
User.init(
  {
    name: {
      type: DataTypes.STRING,
      allowNull: false,
    },
    age: {
      type: DataTypes.INTEGER,
      allowNull: false,
    },
  },
  {
    sequelize,
    modelName: 'User',
    indexes: [
      {
        name: 'name_age_index',
        fields: ['name', 'age'],
        order: 'ASC',
      },
    ],
  }
);

// 查询数据并按照索引进行排序
User.findAll({
  order: [['name', 'ASC'], ['age', 'ASC']],
}).then((users) => {
  console.log(users);
});
