这是我的DaoImpl类。我有其他表tblprofiles，其中字段电子邮件是主键。我可以将电子邮件中的tbldealusers数据作为字符类型的外键。当我运行这个程序时，我得到的错误就像
错误：运算符不存在：character = integer
与tblProfiles具有OneToMany关系的tbldealusers
public class UserDaoImpl implements UserDao
{
private SessionFactory sessionFactory;
DealUser dealuser=new DealUser();
private Session session=null;
Profiles profiles=new Profiles();
@Autowired
public void setSessionFactory(SessionFactory sessionFactory)
{
this.sessionFactory = sessionFactory;
}
@SuppressWarnings("unchecked")
public List<DealUser> getAllDealUsers()
{
session =sessionFactory.getCurrentSession();
List<DealUser> dealUsers = (List<DealUser>) session.
createSQLQuery("select * from tbldealusers u ")
.addEntity("u", DealUser.class)
.list();
return dealUsers;
}
我的执行堆栈跟踪
Hibernate: select * from tbldealusers u
Hibernate: select profiles0_.email as email1_, profiles0_.email as email9_0_, profiles0_.firstnname as firstnname9_0_, profiles0_.lastname as lastname9_0_, profiles0_.mobile as mobile9_0_, profiles0_.notifyflash as notifyfl5_9_0_, profiles0_.is_active as is6_9_0_, profiles0_.tac_preferenceluid as tac7_9_0_, profiles0_.createddate as createdd8_9_0_, profiles0_.modifieddate as modified9_9_0_, profiles0_.createduserid as created10_9_0_, profiles0_.modifieduserid as modifie11_9_0_ from tblprofiles profiles0_ where profiles0_.email=?
