En passant deux paramètres à une requête nommée

Question

je le namedquery suivant sur mon entité « Intervention »:

@NamedQuery(name = "Intervention.findNextMission", query = " SELECT i FROM Intervention i  WHERE i.heureDebut> :DateToBeSpecified and i.idAgent= :idAgent")` 

je ne sais pas comment appeler cette requête dans mon code en passant deux paramètres: la date, id. Normalement, il devrait ressembler à ceci:

List <Intervention> ListOfInterventions = em.createNamedQuery("Intervention.findNextMission").setParameter().getResultList(); 

quoi mettre entre les parenthèses de setParameter() ??

ici suivent le code de mon entité Intervention:

@Entity 
@Table(name = "intervention") 
@XmlRootElement 
@NamedQueries({ 
    @NamedQuery(name = "Intervention.findAll", query = "SELECT i FROM Intervention i"), 
    @NamedQuery(name = "Intervention.findByIdIntervention", query = "SELECT i FROM Intervention i WHERE i.idIntervention = :idIntervention"), 
    @NamedQuery(name = "Intervention.findByHeureDebut", query = "SELECT i FROM Intervention i WHERE i.heureDebut = :heureDebut"), 
    @NamedQuery(name = "Intervention.findByHeureFin", query = "SELECT i FROM Intervention i WHERE i.heureFin = :heureFin"), 
    @NamedQuery(name = "Intervention.findNextMission", query = " SELECT i FROM Intervention i WHERE i.heureDebut> :DateToBeSpecified and i.idAgent= :idAgent")}) 
public class Intervention implements Serializable { 
    private static final long serialVersionUID = 1L; 
    @Id 
    @Basic(optional = false) 
    @NotNull 
    @Size(min = 1, max = 50) 
    @Column(name = "IdIntervention", nullable = false, length = 50) 
    private String idIntervention; 
    @Basic(optional = false) 
    @NotNull 
    @Column(name = "HeureDebut", nullable = false) 
    @Temporal(TemporalType.TIMESTAMP) 
    private Date heureDebut; 
    @Basic(optional = false) 
    @NotNull 
    @Column(name = "HeureFin", nullable = false) 
    @Temporal(TemporalType.TIMESTAMP) 
    private Date heureFin; 
    @Lob 
    @Size(max = 65535) 
    @Column(name = "NotesGeneral", length = 65535) 
    private String notesGeneral; 
    @JoinColumn(name = "IdValidation", referencedColumnName = "IdValidation", nullable = false) 
    @ManyToOne(optional = false) 
    private Tablevalidation idValidation; 
    @JoinColumn(name = "IdNatureIntervention", referencedColumnName = "IdNatureIntervention", nullable = false) 
    @ManyToOne(optional = false) 
    private Tablenatureintervention idNatureIntervention; 
    @JoinColumn(name = "IdAgent", referencedColumnName = "IdAgent", nullable = false) 
    @ManyToOne(optional = false) 
    private Agent idAgent; 
    @JoinColumn(name = "RefContrat", referencedColumnName = "RefContrat", nullable = false) 
    @ManyToOne(optional = false) 
    private Projet refContrat; 

    public Intervention() { 
    } 
    //getters and setters 
} 

Answer 1

setParameter accepte soit (int position,Object value) ou (String parameterName,Object value). Donc, votre code pourrait ressembler à:

Date aDate=.... 
Long anId=.... 
List ListOfInterventions = em.createNamedQuery("Intervention.findNextMission") 
    .setParameter("DateToBeSpecified",aDate,avax.persistence.TemporalType,DATE) 
    .setParameter("idAgent",anId).getResultList(); 

Notez que lorsque vous utilisez un Date vous devez spécifier le TemporalType prévu.
