Bom dia.
Pessoal…
Albuns e Foto … A entidade Albuns tem um List de Foto veja … e quero faze um select aonde me retorne Todos Albuns aonde o atributo publicado da
Foto é igual a ‘SIM’
TENHO ESSE JPQL QUE LISTA OS ALBUNS , só que ele lista com atributo publicado SIM, mesmo que esteja NAO, ou seja “parece” que ele ignora a clausula " f.publicado = :p"
public List<Album> buscarAlbunsDoCliente(Integer idCliente) throws Exception {
em = getEntityManager();
List<Album> albuns = new ArrayList<Album>();
try {
Query consultaCliente = em.createQuery("SELECT p FROM Pessoa p WHERE p.id = :id ");
consultaCliente.setParameter("id", idCliente);
Pessoa pessoa = (Pessoa) consultaCliente.getSingleResult();
if (pessoa.getPerfil().equals(Perfil.ADMINISTRADOR)) {
Query consulta = em.createQuery("SELECT DISTINCT a from Album a INNER JOIN a.fotos f WHERE f.publicado = :p ");
consulta.setParameter("p", Publicado.SIM);
albuns = consulta.getResultList();
} else {
Query consulta = em.createQuery("SELECT DISTINCT a from Album a INNER JOIN a.fotos f WHERE f.publicado = 'SIM' AND a.cliente.id = :id ");
consulta.setParameter("id", idCliente);
albuns = consulta.getResultList();
}
} catch (Exception e) {
e.printStackTrace();
throw e;
} finally {
em.close();
return albuns;
}Ja este SELECT
Query consulta = em.createQuery("SELECT a FROM Album a WHERE a.fotos.publicado = :p ");
consulta.setParameter("p", Publicado.SIM);
abuns = consulta.getResultList(); porem gera este EXCEÇÃO
java.lang.IllegalArgumentException: org.hibernate.QueryException: illegal attempt to dereference collection [album0_.id.fotos] with element property reference [publicado] [SELECT a FROM entidades.Album a WHERE a.fotos.publicado = :p ]
