Pessoal estou fazendo um “SELECT” simples com JPQL ou SQL (“testei com os dois”), veja as instruções:
JPQL : - Query consulta = em.createQuery(“SELECT albuns FROM Album album where album.cliente.id = :id”);
SQL : - Query consulta = em.createNativeQuery(“SELECT * FROM album WHERE cliente_id = :id”)
Independente de ser SQL ou JPQL gera a seguinte exceção
Exceção - GRAVE: java.lang.IllegalStateException: No data type for node: org.hibernate.hql.ast.tree.IdentNode
-[IDENT] IdentNode: ‘albuns’ {originalText=albuns}
A instrução SQL eu testei no meu banco de dados(MySql) e funcionou certinho, não sei o que pode ser.
Veja o detalhamento do meu código
Classe Album
@Entity
@Table(name = "Album")
public class Album implements Serializable{
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "id", nullable = false)
private Integer id;
@OneToOne(cascade=CascadeType.DETACH)
private Pessoa cliente;
@OneToMany(cascade=CascadeType.ALL , fetch=FetchType.EAGER)
@JoinColumn(name="fotos", referencedColumnName="id")
@Column(name = "fotos", nullable = false)
private List<Foto> fotos;
@Column(name = "descricao", nullable = true)
private String descricao;
//Construtor
public Album(){
this.setCliente(new Pessoa());
this.setFotos(new ArrayList<Foto>());
}
//Get e Set
public Pessoa getCliente() {
return cliente;
}
public void setCliente(Pessoa cliente) {
this.cliente = cliente;
}
public String getDescricao() {
return descricao;
}
public void setDescricao(String descricao) {
this.descricao = descricao;
}
public List<Foto> getFotos() {
return fotos;
}
public void setFotos(List<Foto> fotos) {
this.fotos = fotos;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
}Meu método que usa este select
public class AlbumDAO extends Dao {
public List<Album> buscarAlbunsDoCliente(Integer idCliente) throws Exception{
em = emf.createEntityManager();
List<Album> albuns = new ArrayList<Album>();
try {
em.getTransaction().begin();
Query consulta = em.createNativeQuery("SELECT * FROM album WHERE cliente_id = :id");
// Ou JPQL : Query consulta = em.createQuery("SELECT albuns FROM Album album where album.cliente.id = :id");
consulta.setParameter("id", idCliente);
albuns = consulta.getResultList();
em.getTransaction().commit();
} catch (Exception e) {
e.printStackTrace();
em.getTransaction().rollback();
throw e;
} finally {
em.close();
return albuns;
}
}
}
