Hibernate3中可以直接通过面向对象的形式进行条件删除，或者是直接sql的形式进行批量删除。
Sql代码：
Session session=HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
String strSQL=" delete from Classes as a where a.classno like :name";
Query query = session.createQuery(strSQL);
query.setString("name", "%"+OId+"%");
Session session=HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
String strSQL="from Classes as a where a.classno like :name";
Query query = session.createQuery(strSQL);
HQL代码：
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
List result=session.createQuery("delete from Classes as a where a.classno
like " '%"+OId+"%'").list();
[sql] view plaincopyprint?
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
List result=session.createQuery("from Classes as a where a.classno like " '%"+OId+"%'").list();
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
String result=session.createQuery("delete from Classes as a where a.classno like " '%"+OId+"%'").list();
