Question

I got class:

@Entity
@Table(name="restaurants")
public class Restaurant {
    @Id
    @GeneratedValue
    private int id;
    private String name;
    private String street;
    (...)
    @ManyToMany
    @JoinTable(name="user_restaurant_owner",
            joinColumns={@JoinColumn(name="restaurant_id")},
            inverseJoinColumns={@JoinColumn(name="username")})
    private List<User> owner;

How to get Restaurant if I know User (“owner”) username?

Query q = session.createQuery(“from Restaurant as r where r.owner = :username”).setString(“username”, username);

it doesn;t work

Answer 1

You need to join to a collection in HQL if you are selecting on properties of the element within the collection.

from Restaurant r join r.owner o where o.username = :username
