連接查詢不處於休眠

工作我使用hibernate-session.createQuery()執行的inner-join查詢，我得到了錯誤：連接查詢不處於休眠

我的查詢是：

select dist.districtName, dist.status, stat.stateName from sa_district_master dist inner join sa_state_master stat on dist.stateId = stat.stateId

但是，如果我執行相同的查詢我-SQL控制檯，它完美地執行，並給予O/P：

+--------------+--------+-----------+ 
| districtName | status | stateName | 
+--------------+--------+-----------+ 
| Hisar  | 0  | HARYANA | 
| Gurgaon  | 0  | HARYANA | 
| Ambala  | 0  | HARYANA | 
| Rohtak  | 0  | HARYANA | 
| Sirsa  | 0  | HARYANA | 
+--------------+--------+-----------+

我的Hibernate代碼：

try{ 
     hibernateSession = HibernateUtil.getSession(); 
     if(hibernateSession != null){ 
      Query query = hibernateSession.createQuery("select dist.districtName, dist.status, stat.stateName from sa_district_master dist inner join sa_state_master stat on dist.stateId = stat.stateId"); 
      List list = query.list(); 
      for (Object object : list) { 
       Object[] objArray = (Object[])object; 
       System.out.println("Obj : " + objArray[0]); 
      } 
     } 
    } catch (Exception e){ 
     e.printStackTrace(); 
    }finally { 
     hibernateSession.flush(); 
     hibernateSession.close(); 
    }

我不明白爲什麼我得到的錯誤...

plzzz幫助...

變化'hibernateSession.createQuery'到'hibernateSession。 createSQLQuery' –

您的查詢似乎更像是一個標準的SQL查詢比一個HQL查詢。使用Session#createSQLQuery(String sqlQuery)方法創建一個像這樣的SQL查詢。

Query query = hibernateSession.createSQLQuery("select dist.districtName, dist.status, stat.stateName from sa_district_master dist inner join sa_state_master stat on dist.stateId = stat.stateId");

您使用的是SQL查詢，所以你需要爲MySQL創建一個SQLQuery

try{ 
    hibernateSession = HibernateUtil.getSession(); 
    if(hibernateSession != null){ 
     Query query = hibernateSession.createSQLQuery("select dist.districtName, dist.status, stat.stateName from sa_district_master dist inner join sa_state_master stat on dist.stateId = stat.stateId"); 
     List list = query.list(); 
     for (Object object : list) { 
      Object[] objArray = (Object[])object; 
      System.out.println("Obj : " + objArray[0]); 
     } 
    } 
} catch (Exception e){ 
    e.printStackTrace(); 
}finally { 
    hibernateSession.flush(); 
    hibernateSession.close(); 
}

Query query = hibernateSession.createSQLQuery("select dist.districtName, dist.status, stat.stateName from sa_district_master dist inner join sa_state_master stat on dist.stateId = stat.stateId");

使用.createSQLQuery方法
