在Hibernate中执行mysql查询作为本机查询

Question

我是Hibernate的新手。我正在使用JSF，Spring和Hibernate创建一个Web应用程序。我想实现从使用用户过滤器生成该查询休眠

select * from (Select DATE_FORMAT(a.call_offered_time,'%d %b %Y %k:%i:%s') As 'call_date', a.caller_id as 'Caller', DATE_FORMAT(a.call_offered_time,'%d %b %Y %k:%i:%s') as 'Call Connected', DATE_FORMAT(a.call_disconnect_time,'%d %b %Y %k:%i:%s') as 'Call Disconnected',a.channel_no as 'Channel', a.call_status as 'Call Status', (Case When a.call_routed_to_agent=Null or a.call_routed_to_agent='' then 'IVRS' Else call_routed_to_agent End) as 'Call Routed To', b.ddi,TIMESTAMPDIFF(SECOND,a.call_offered_time,a.call_disconnect_time) as 'Duration'from CallDetail a,ddi_details b Where a.call_reference_no =b.call_reference_no and a.call_offered_time Between '2006-01-01 00:00:00' And '2010-11-20 23:59:00') as t order by STR_TO_DATE(t.call_date,'%d %b %Y %k:%i:%s') 

为此，我尝试下面的代码

Session session = null; 
    // This step will read hibernate.cfg.xml and prepare hibernate for use 
    SessionFactory sessionFactory = this.getSessionFactory(); 

    session =sessionFactory.openSession(); 



    //Create Select Clause HQL 
    String SQL_QUERY ="select * from (Select DATE_FORMAT(a.call_offered_time,'%d %b %Y %k:%i:%s') As 'call_date', " + 
         "a.caller_id as 'Caller', DATE_FORMAT(a.call_offered_time,'%d %b %Y %k:%i:%s') as " + 
         "'Call Connected', DATE_FORMAT(a.call_disconnect_time,'%d %b %Y %k:%i:%s') as " + 
         "'Call Disconnected',a.channel_no as 'Channel', a.call_status as 'Call Status', " + 
         "(Case When a.call_routed_to_agent=Null or a.call_routed_to_agent='' then 'IVRS' " + 
         "Else call_routed_to_agent End) as 'Call Routed To', b.ddi," + 
         "TIMESTAMPDIFF(SECOND,a.call_offered_time,a.call_disconnect_time) as " + 
         "'Duration'from CallDetail a,iss_master.ddi_details b Where " + 
         "a.call_reference_no =b.call_reference_no and a.call_offered_time Between " + 
         "'2006-01-01 00:00:00' And '2010-11-20 23:59:00') as t order by STR_TO_DATE(t.call_date,'%d %b %Y %k:%i:%s')"; 

    System.out.println(SQL_QUERY); 

    Query query = session.createSQLQuery(SQL_QUERY).addEntity(InboundCallDetail.class); 

    List result = query.list(); 

当我运行这段代码，我得到以下错误

由于提前，

P.S之所以如此是由通过过滤器的用户产生在查询中的“地点”状况的报告应用程序。

我的更新Java代码为FO llows

@PersistenceContext private EntityManager em; 
EntityManagerFactory emf = Persistence.createEntityManagerFactory("myapp"); 

em = emf.createEntityManager(); 
Query query = em.createNativeQuery(SQL_QUERY); 

请纠正我的问题。感谢您的更新！

更新

我试图通过@ckuetbach的建议和我的应用程序context.xml文件添加

请纠正我的错误！

Answer 1

如果你想执行MySQL查询在休眠本地查询，你可以使用createNativeQuery()

Answer 2

我想你错过了包括映射到你的实体。您必须为您的所有实体创建和添加映射文件。

<property name="mappingResources"> 
    <list> 
     <value> 
      com/address/Address.hbm.xml 
     </value>     
     <value> 
      com/address/InboundCallDetail.hbm.xml 
     </value>  
    </list> 
</property> 

第二个问题似乎是，你没有设置休眠方言Hibernate Dialect must be explicitly
