hql更新语句怎么搞的
————————createQuery里面的语句好像不正确--------------
public void updateInfo(String username, String repassword,String reemail){
Session session=(Session) this.getSession();
session.beginTransaction();
Query query = session.createQuery("update User a set a.password =? set a.email=? where a.username =?");
query.setString(0, repassword);
query.setString(1, username);
query.setString(2, reemail);
query.executeUpdate();
session.getTransaction().commit();
}
}
[解决办法]
TRy
update User a set a.password =? set a.email=? where a.username =?");
update User a , a.password =? , a.email=? where a.username =?");
[解决办法]
update User a set a.password =? , a.email=? where a.username =?");
[解决办法]
update User a set a.password =?, a.email=? where a.username =?

hibernate 里有封装好的更新
saveOrUpdate(实体类);【是通过是否有主键 例如：id 来判断是更新还是增加】
有主键值 就更新 没主键就增加一个
