LeftJoinAndSelect is not working when using SubQueryFactory

Issue type:

• documentation issue
• bug report

Database system/driver:

• mysql / mariadb

TypeORM version:

• latest 0.2.26

What is the proper way to create the following query?

SELECT user.*, photos.*
FROM user
LEFT JOIN 
    (SELECT * FROM user_photos ORDER BY updatedAt LIMIT 5) AS photos
    ON user.id = photos.userId

The best I have tried using SubQueryFactory

const result = await userRepo
      .createQueryBuilder('user')
      .leftJoinAndSelect(
        qb => qb
          .select()
          .from(UserPhotos, 'p')
          .orderBy({ 'p.updatedAt': 'ASC' })
          .limit(5),
        'photos'
      )
      .getMany()

This code generated this query (SIMPLIFIED)

SELECT user.*, photos.* 
FROM user
LEFT JOIN
    (SELECT * FROM `user_photos` `p` ORDER BY p.updatedAt ASC LIMIT 5) AS photos
    --- 🤨 where is ON clause?

Where is the ON clause 🤨?

You can see that everything is ok until the ON clause. When I don’t use SubQueryFactory everything is ok.

Not using SubQueryFactory (IS NOT A SOLUTION)

const result = await userRepo
      .createQueryBuilder('user')
      .leftJoinAndSelect('user.photos', 'photos')
      .getMany()

ON is right there

SELECT user.*, photos.* 
FROM user
LEFT JOIN `user_photos` `photos` 
    ON photos.userId = user.id --- see?

@imnotjames this is working as intended, but when I get raw query result using getRawOne() it’s giving the joined data but when I use getOne() it’s returning blank data for that column. I even tried to use leftJoinAndMapOne but it’s still not working. https://github.com/typeorm/typeorm/issues/5637#issuecomment-699087519
