How to select only single/multiple fields from joined entity in Typeorm
const user = await createQueryBuilder("user") .leftJoinAndSelect("user.photos", "photo") .select(['user', 'photo.url', 'photo.alt']) .where("user.name = :name", { name: "Timber" }) .getOne();or
const user = await createQueryBuilder("user") .leftJoinAndSelect("user.photos", "photo") .addSelect(['photo.url', 'photo.alt']) .where("user.name = :name", { name: "Timber" }) .getOne();(not sure about the second one)
The first answer given by Art Olshansky is right (the second one doesn't), so, you must stand "the base" entity but, if you don't need all/any user fields you can just apply
const user = await createQueryBuilder("user") .leftJoinAndSelect("user.photos", "photo") .select(['user.id', 'photo.url', 'photo.alt']) .where("user.name = :name", { name: "Timber" }) .getOne();
