Entity mapped to a view shows wrong Information

created by Osvaldo González in EJB 3.0 - View the full discussion

Hi everybody. I have made a view in my MySQL Database to fetch some data to present to the user, but when I try to retrieve the data from that view with an entity what I get is not the same that I can see in my database. Here is the code to the view:

 


DROP VIEW IF EXISTS `copladem`.`confdependencias`;
DROP VIEW IF EXISTS `copladem`.`confdependencias`;
CREATE OR REPLACE ALGORITHM=UNDEFINED DEFINER=`root`@`localhost` SQL SECURITY DEFINER VIEW `confdependencias`

AS select `configuraciones`.`Nombre` AS `Configuracion`,`dependencias`.`nombre` AS `Dependencia`,
if((count(`configuracionesdependencias`.`idConfiguracionesDependencias`) > 0),'SI','NO') AS `Existe`
from ((`dependencias` join `configuraciones` on((`configuraciones`.`idConfiguracion` = 
`configuraciones`.`idConfiguracion`))) left join `configuracionesdependencias` 
on(((`configuracionesdependencias`.`configuracion` = `configuraciones`.`idConfiguracion`) 
and (`configuracionesdependencias`.`dependencia` = `dependencias`.`idDependencia`)))) 
group by `dependencias`.`nombre`,`configuraciones`.`Nombre` order by `configuraciones`.`Nombre`;
CREATE OR REPLACE ALGORITHM=UNDEFINED DEFINER=`root`@`localhost` SQL SECURITY DEFINER VIEW `confdependencias` AS select `configuraciones`.`Nombre` AS `Configuracion`,`dependencias`.`nombre` AS `Dependencia`,if((count(`configuracionesdependencias`.`idConfiguracionesDependencias`) > 0),'SI','NO') AS `Existe` from ((`dependencias` join `configuraciones` on((`configuraciones`.`idConfiguracion` = `configuraciones`.`idConfiguracion`))) left join `configuracionesdependencias` on(((`configuracionesdependencias`.`configuracion` = `configuraciones`.`idConfiguracion`) and (`configuracionesdependencias`.`dependencia` = `dependencias`.`idDependencia`)))) group by `dependencias`.`nombre`,`configuraciones`.`Nombre` order by `configuraciones`.`Nombre`;


 

With this view, executed in MySQL Query Browser, I get the follow:

http://community.jboss.org/servlet/JiveServlet/downloadImage/2-568898-10551/450-70/view.JPG

That's just what I want, so I generated an entity from this view using netbeans, it looks like this:

 

@Entity
@Table(name = "confdependencias")
@NamedQueries({
    @NamedQuery(name = "Confdependencias.findAll", query = "SELECT c FROM Confdependencias c"),
    @NamedQuery(name = "Confdependencias.findByConfiguracion", query = "SELECT c FROM Confdependencias c WHERE c.configuracion = :configuracion"),
    @NamedQuery(name = "Confdependencias.findByDependencia", query = "SELECT c FROM Confdependencias c WHERE c.dependencia = :dependencia"),
    @NamedQuery(name = "Confdependencias.findByExiste", query = "SELECT c FROM Confdependencias c WHERE c.existe = :existe")})
public class Confdependencias implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id
    @Basic(optional = false)
    @Column(name = "Configuracion")
    private String configuracion;
    @Basic(optional = false)
    @Column(name = "Dependencia")
    private String dependencia;
    @Basic(optional = false)
    @Column(name = "Existe")
    private String existe;
    /*CONSTRUCTOR, GETTER's AND SETTER's*/
}

 

And then I Tried to get data using this:

Query q;
q = em.createNamedQuery("Confdependencias.findAll");

 

But when I see the q.getResultList() method, it returns a vector of Confdependencias objects with the follow data:

 

configuraciondependenciaexiste

As You can see, it's not the information that the view shows in the database, so, what I'm doing wrong? Thanks for your help
