hibernate的获取返回值的问题

[上去就一个404]

public Long getCompanyIdByUser(Long id) {
		Session session  = sessionFactory.getCurrentSession();
		Query q = session.createQuery("select companyId from USER   where  id=?id"); 
		Long Companyid = (Long)q.uniqueResult(); 
		return Companyid;
	}

我这样写获取不到我想要的查询结果,请问应该怎么写呢

[自由自在_Yu]

Query q = session.createQuery("select companyId from USER where id=?id"); Query q = session.createQuery("select companyId from USER where id=?" + id);

引用 1 楼 yuxiangaaaaa 的回复:

Query q = session.createQuery("select companyId from USER where id=?id"); Query q = session.createQuery("select companyId from USER where id=?" + id);

Query q = session.createQuery("select companyId from USER where id=" + id);

[quote=引用 1 楼 yuxiangaaaaa 的回复:] Query q = session.createQuery("select companyId from USER where id=?id"); Query q = session.createQuery("select companyId from USER where id=?" + id);

Query q = session.createQuery("select companyId from USER where id=" + id);[/quote] 这个不行

Query q = session.createQuery("select companyId from USER u where u. id=" + id);
