我是Hibernate的新手。我正在使用JSF，Spring和Hibernate创建一个Web应用程序。我正在尝试使用hibernate
实现从用户过滤器生成的此查询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，我尝试了以下代码
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();
当我运行此代码时，我收到以下错误

请纠正我的错误或建议其他方法。
提前致谢，
P.S这是一个报告应用程序，因此用户可以通过过滤器生成查询中的“where”条件。
更新 对不起，来晚了！ 由于我使用Spring和Hibernate创建了应用程序，所以我没有创建hibernate-config.xml而是在application-context.xml中提供了详细信息

我更新的java代码如下
@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
我按照@ckuetbach的建议尝试了，我添加了
<value>
com/address/InboundCallDetail.hbm.xml
</value>
在application-context.xml文件中
现在我收到此错误

请纠正我的错误！
答案 0 :(得分：6)
如果你想在Hibernate中执行mysql查询作为本机查询，你可以使用createNativeQuery()
答案 1 :(得分：1)
我认为您错过了向您实体添加映射。您必须为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Hibernate Dialect Hibernate Dialect must be explicitly
