Pessoal, tenho uma duvida, eu estou tentando trazer algumas colunas especificas do meu bd, e criei uma Query JPQL , para fazer está busca para mim o problema é que para mim parece estar tudo certo, mas sempre retorna o erro, poderiam dar uma olhada?
Essa é @NamedQuery
@NamedQueries({
@NamedQuery(name = "Ajudante.findDTO", query = "SELECT a.idUsuario, a.email,a.nome,a.salarioBase,a.salarioComissao FROM Ajudante as a") })
e está é a chamada no DAO:
public List<Ajudante> buscaSimples() {
List<Ajudante> recebe = em.createNamedQuery("Ajudante.findDTO", Ajudante.class).getResultList();
System.out.println(recebe);
return recebe;
}
e está é exception:
> org.jboss.resteasy.spi.UnhandledException: java.lang.IllegalArgumentException: Cannot create TypedQuery for query with more than one return using requested result type [br.com.teste.entites.Ajudante]
