HSQLDB Sortuj według z wieloma kolumnami

Question

Wykonuję kwerendę przy użyciu hsqldb i hibernacji. Mam zamówienie stwierdzeniem: -

Query query = em 
    .createQuery("SELECT DISTINCT new com.mytransferobject.QuickSearchResultTO(m.id, m.firstName||' '||m.surname, '') " + 
     "FROM Member m, ClassC c, ClassCm cm " + 
     "WHERE c.id = cm.clubId AND m.id = cm.memberId " + 
     "AND c.lft >= :lft AND c.lft <= :rgt " + 
     "AND (firstName LIKE :memberName OR surname LIKE :memberName) " + 
     "AND m.deleted = false " + 
     "AND c.deleted = false " + 
     "ORDER BY m.firstName, m.surname"); 

query.setParameter("lft", lft); 
query.setParameter("rgt", rgt); 
query.setParameter("memberName", memberName + "%"); 

Działa to dobrze w MySQL, ale nie w moim kodu testowego (używając hsqldb 2.2.6). Próbowałem połączyć je razem i działa dobrze, ale jest to bardzo często używane zapytanie, więc chciałbym uniknąć niepotrzebnych operacji.

otrzymuję wyjątek: -

Answer 1

Prawdopodobnie masz wyjątku „invalid zamówienie przez ekspresję”, ponieważ można określić kolumny w kolejności (w przypadku, m.firstName i m.surname), które nie są jawnie zwracane w klauzuli SELECT. Niektóre bazy danych, takie jak SQL Server i MySQL, nie potrzebują tego, ale inne, takie jak HSQLDB i DB2, nie mogą tego dokonać ORDER BY bez pól w SELECT.

Myślę, że Twój kod będzie działać, jeśli używasz:

Query query = em 
    .createQuery("SELECT DISTINCT new com.mytransferobject.QuickSearchResultTO(m.id, m.firstName, m.surname, m.firstName||' '||m.surname, '') " + 
     "FROM Member m, ClassC c, ClassCm cm " + 
     "WHERE c.id = cm.clubId AND m.id = cm.memberId " + 
     "AND c.lft >= :lft AND c.lft <= :rgt " + 
     "AND (firstName LIKE :memberName OR surname LIKE :memberName) " + 
     "AND m.deleted = false " + 
     "AND c.deleted = false " + 
     "ORDER BY m.firstName, m.surname"); 

Answer 2

miałem ten sam problem, naprawiłem go przy użyciu GROUP BY zamiast odrębnych, zwróci ten sam rezultat. Twój kod zadziała, jeśli użyjesz:

Query query = em 
.createQuery("SELECT new com.mytransferobject.QuickSearchResultTO(m.id, m.firstName||' '||m.surname, '') " + 
    "FROM Member m, ClassC c, ClassCm cm " + 
    "WHERE c.id = cm.clubId AND m.id = cm.memberId " + 
    "AND c.lft >= :lft AND c.lft <= :rgt " + 
    "AND (firstName LIKE :memberName OR surname LIKE :memberName) " + 
    "AND m.deleted = false " + 
    "AND c.deleted = false " + 
    "GROUP BY m.idORDER BY m.firstName, m.surname");
