我已经尝试了很多使用hql更新我的表但我没有找到解决方案,我也在互联网上搜索过,我是java和hibernate的新手请帮我找到解决方案.
我的代码写在下面.
session.getTransaction().begin();
Query query = session.createQuery("update DocDetail set DocName = :docname" +
" where Id = :docId");
query.setParameter("docname", "Jack");
query.setParameter("docId", 3);
int result = query.executeUpdate();
session.getTransaction().commit();
但我得到以下错误.
Exception in thread "AWT-EventQueue-0" org.hibernate.QueryException: query must begin with SELECT or FROM: update [update clinic.entity.DocDetail set DocName = :studentName where Id = :studentId]
