Question

A User is 1-to-1 with Car. But User not always has a Car.

query = session.createQuery("select u from User as u join fetch u.car");

I get only users with cars. How do i modify this query to get all users?

I’m using fetch because i need user.car outside of the session, am i doing this right?

Thanks.

Use a left join, which was designed for this express purpose.

query = session.createQuery("select u from User as u left join fetch u.car");
