Hibernate multiple subqueries with DetachedCriteria - mysql

Question

I would like write this query into HQL :
select DISTINCT * from transportation transp
inner join price p on p.transportationId = transp.transportationId
where p.sectionId = ( select sec.sectionId from section sec where sec.lineId = ( select l.lineId from line l where l.lineId = 1000000000) )
But don't know write subqueries. I know I must use DetachedCriteria.
An other question:
If we can write this query in native query (using createSQLQuery), how can cast returned objet to Transportation entity ?
Thanks
My entities :
#Entity
#Table(name = "transportation")
public class Transportation implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "transportationId")
private Integer id;
#OneToMany(mappedBy = "transportation", fetch = FetchType.EAGER)
#JsonBackReference(value = "price-transportation")
private Set<Price> prices = new HashSet<Price>();
...
}
#Entity
#Table(name = "price")
public class Price implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "priceId")
private Integer id;
#ManyToOne(optional = false)
#JoinColumn(name = "transportationId")
#JsonManagedReference(value = "price-transportation")
private Transportation transportation;
...
}
#Entity
#Table(name = "section")
public class Section implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "sectionId")
private Integer id;
#ManyToOne(optional = false)
#JoinColumn(name = "lineId")
#JsonManagedReference
private Line line;
...
}
#Entity
#Table(name = "line")
public class Line implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "lineId")
private Integer id;
#OneToMany(mappedBy = "line", cascade = CascadeType.ALL, fetch = FetchType.EAGER)
#JsonBackReference
private Set<Section> sections = new HashSet<Section>();
...
}

Answer 1

I solved my issue by using .addEntity(Transportation.class) like this :
String query = "select DISTINCT * from moyen_transport transp"
+ " join prix_voyage p on p.ID_MoyenTransport = transp.ID_MoyenTransport"
+ " where p.ID_Troncon = ( select t.ID_Troncon from troncon t where t.ID_Troncon = ( select l.ID_Ligne from ligne l where l.ID_Ligne = 1000000000) )";
Query result = getSession().createSQLQuery(query).addEntity(Transportation.class)**;
List<Transportation> results = result.list();
