Hi all,
following the article [url=Use Hibernate’s Custom Loaders to fake an aggregation view]http://www.cereslogic.com/pages/2008/06/23/use-hibernates-custom-loaders-to-fake/[/url] i'm trying to make work my "fake view".
Here's my code: (the property names are in Italian, but their meaning is not 'important)
Code:
@javax.persistence.Entity
@Entity(dynamicInsert=false, dynamicUpdate=false, mutable=false)
@Loader(namedQuery="loadArticoloView")
@SqlResultSetMapping(name="loadArticoloView",
entities=@EntityResult(entityClass=ArticoloView.class))
@NamedNativeQuery(name="loadArticoloView",
query="select " +
"a.id as id, nome, descrizione, posizione, prezzo, coefficientePrezzo, prezzoFinito, " +
"c.testo as categoria, " +
"m.quantita as quantita, " +
"(select nome" +
"from " +
"articolo_fattura " +
"left join fornitore on articolo_fattura.id_fornitore = fornitore.id " +
"where id_articolo = a.id " +
"order by data_fattura DESC " +
"limit 0,1) as fornitore " +
"from " +
"articolo a " +
"left join codcategoria c on c.id = a.id_categoria " +
"left join magazzino m on m.id_articolo = a.id " +
"where a.id = ?",
resultSetMapping="loadArticoloView")
public class ArticoloView {
String id;
String nome;
String descrizione;
String posizione;
Float prezzo;
Float coefficientePrezzo;
Float prezzoFinito;
String categoria;
Integer quantita;
String fornitore;
@Id
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
// getter and setter...
}
and i'm trying to do this:
Code:
Query q = em.createQuery("Select count(*) from ArticoloView", Long.class);
System.out.println(q.getResultList().get(0).toString());
hibernate instead execute this query :
Code:
select count(*) as col_0_0_ from ArticoloView articolovi0_
and seem to ignore mine.
in the console outpout i've found : (I do not know if it means something)
Code:
1621 [http-8080-2] INFO org.hibernate.cfg.AnnotationBinder - Binding entity from annotated class: com.example.testhibernate3.hibernate.view.ArticoloView
1624 [http-8080-2] INFO org.hibernate.cfg.annotations.QueryBinder - Binding named native query: loadArticoloView => select a.id as id, nome, descrizione, posizione, prezzo, coefficientePrezzo, prezzoFinito, c.testo as categoria, m.quantita as quantita, (select nomefrom articolo_fattura left join fornitore on articolo_fattura.id_fornitore = fornitore.id where id_articolo = a.id order by data_fattura DESC limit 0,1) as fornitore from articolo a left join codcategoria c on c.id = a.id_categoria left join magazzino m on m.id_articolo = a.id where a.id = ?
1625 [http-8080-2] INFO org.hibernate.cfg.annotations.EntityBinder - Bind entity com.example.testhibernate3.hibernate.view.ArticoloView on table ArticoloView
Someone know where's my error ?
