org.hibernate.hql.internal.ast.QuerySyntaxException: Двигатель не отображается [от двигателя, где VNOPOL =: ID]

Question

У меня есть проблема в отображении:

Motor. Java

public void fullInfo() { 
     MotorDao dao = new MotorDao(); 
     List<Motor> lc = dao.getMotorById(VNOPOL); 
     System.out.println(lc.get(0).VNOPOL); 
     this.VIDCUSTOMER = lc.get(0).VIDCUSTOMER; 
     this.VFRAMENUM = lc.get(0).VFRAMENUM; 
     this.VENGINENUM = lc.get(0).VENGINENUM; 
     this.VTHNPROD = lc.get(0).VTHNPROD; 
     this.NKMSERVICE = lc.get(0).NKMSERVICE; 

    } 

MotorDao.java:

public List<Motor> getMotorById(String motid) { 
     System.out.println(motid); 
//  Customer cust = null; 
     Transaction trns = null; 
     Session session = HibernateUtil.getSessionFactory().openSession(); 
     try { 
      trns = session.beginTransaction(); 
      String queryString = "from Motor where VNOPOL = :id"; 
      Query query = session.createQuery(queryString); 
      query.setString("id", motid); 
      //cust = (Customer) query.uniqueResult(); 
      List<Motor> list = query.list(); 
      if (list.size() > 0) { 
       return list; 
      } 
     } catch (RuntimeException e) { 
      e.printStackTrace(); 
     } finally { 
      session.flush(); 
      session.close(); 
     } 
     return null; 
    }

запроса "от Motor" является имя_классом. Но его все еще не работает. Как запросить его по идентификатору VNOPOL?

Answer 1

Попробуйте изменить запрос:

String queryString = "from ahmdsmts_mstmotor where VNOPOL = :id";
