Hello friends.

I'm trying to run a native sentence to get records, but I get an error, which refers to primary keys are null when no records with null key in my table ("Alergia").

Code to execute sentence:
getEntityManager().createNativeQuery("SELECT a FROM Alergia a", com.os.ud.entities.Alergia.class).getResultList()


Entity:
@Entity
@Table(name = "alergia")
@XmlRootElement
@NamedQueries({@NamedQuery(name = "Alergia.findAll", query = "SELECT a FROM Alergia a"),
    @NamedQuery(name = "Alergia.findByCodigo", query =
    "SELECT a FROM Alergia a WHERE a.codigo = :codigo"),
    @NamedQuery(name = "Alergia.findByNombre", query =
    "SELECT a FROM Alergia a WHERE a.nombre = :nombre"),
    @NamedQuery(name = "Alergia.findByDescripcion", query =
    "SELECT a FROM Alergia a WHERE a.descripcion = :descripcion")})
public class Alergia implements Serializable {

    private static final long serialVersionUID = 1L;
    @TableGenerator(name = "Ale_Gen", table = "id_gen", pkColumnName = "gen_name",
    valueColumnName = "gen_val", allocationSize=1)
    @Id @GeneratedValue(generator="Ale_Gen")
    @Basic(optional = false)
    @NotNull
    @Column(name = "codigo")
    private Integer codigo;
    @Size(max = 50)
    @Column(name = "nombre")
    private String nombre;
    @Size(max = 200)
    @Column(name = "descripcion")
    private String descripcion;
    @ManyToMany(mappedBy = "alergiaList")
    private List<Paciente> pacienteList;
    //


    public Alergia() {
    }


    public Alergia(Integer codigo) {
        this.codigo = codigo;
    }


    public Integer getCodigo() {
        return codigo;
    }


    public void setCodigo(Integer codigo) {
        this.codigo = codigo;
    }

....

However, the following code works well, and should get the same records as the code above.
getEntityManager().createNamedQuery("Alergia.findAll", com.os.ud.entities.Alergia.class).getResultList()



Can you help me?

Thank You, very much

I screwed up.
I'm so sorry.
I hope you haven't wasted your time.

I had to be used "createQuery" instead of "createNativeQuery."

Thank you.
