TypeORM: Sort Results by a Relation Column

Updated: January 30, 2024 By: Pennywise Post a comment

When using TypeORM to interact with databases, there might be occasions when you want to take records and sort them based on a relational field. There are 2 solutions for this: using find options and using a query builder. Let’s see the example below for more clarity.

The Example

In this example, we have 2 entities: User and Post. The relationship between them is One-To-Many/Many-To-One. Our goal is to retrieve all posts in ascending order of user age ((or descending order, if you prefer).

Defining Entities

User entity:

// KindaCode.com
// User entity
import { Entity, PrimaryGeneratedColumn, Column, OneToMany } from 'typeorm';
import { Post } from './Post';

export class User {
  id: number;

  name: string;

  @Column({nullable: true})
  age: number;

  @OneToMany(type => Post, post => post.user)
  posts: Post[];

Post entity:

// KindaCode.com Example
// Post entity
import { Entity, Column, PrimaryGeneratedColumn, ManyToOne } from 'typeorm';
import { User } from './User';

export class Post {
  id: number;

  @ManyToOne((type) => User, (user) => user.posts, { cascade: true })
  user: User;

  title: string;

  body: string;

Using Find Options

This approach works for TypeORM 0.3 and newer. For older versions, consider using a query builder instead.

With the code snippet below, posts by younger users will appear first:

const postRepository = myDataSource.getRepository(Post);

const posts = await postRepository.find({
      relations: {
        user: true,
      order: {
        user: {
          age: 'ASC',


Using Query Builder

This code does the something as the previous snippet:

const postRepository = myDataSource.getRepository(Post);

const posts = await postRepository
      .leftJoinAndSelect('post.user', 'user')
      .orderBy('user.age', 'ASC')



We’ve walked through a couple of different ways to get data from the database in order of a relation column. This knowledge is helpful when you have to deal with complex databases with relationships between tables.
