Я работаю над функциональностью, где мне нужно получить данные из БД на основе даты. Формат даты в БД - гггг-мм-дд, и в моем приложении я передаю дату в той же форме.
Столбец дня в классе сущностей TempTable - Дата (java .util.Date) , Я также использовал Temporal, но безуспешно.
Ниже приведен код java:
EntityManagerFactory emf= Persistence.createEntityManagerFactory("punit");
EntityManager em = emf.createEntityManager();
Query query;
query = em.createQuery("select r from TempTable r where r.uId = :uid and r.day = :day group by r.mId, r.rId");
query.setParameter("uid", 5l);
SimpleDateFormat simpleDateFormat= new SimpleDateFormat("yyyy-MM-dd");
Date d = simpleDateFormat.parse("2018-10-12");
query.setParameter("day", d);
query.getResultList();
После выполнения кода обнаружил исключение, как показано ниже:
