求视HQL语句 结果为什么没有limit这部分

(List<Question>) session.createQuery("from Question q where q.teacher.id='"+teacherId+"' order by q.id asc limit "
                  + pagePos + "," + pageSize).list();

 select
        question0_.id as id3_,
        question0_.answer as answer3_,
        question0_.category_id as category10_3_,
        question0_.choice_a as choice3_3_,
        question0_.choice_b as choice4_3_,
        question0_.choice_c as choice5_3_,
        question0_.choice_d as choice6_3_,
        question0_.createDate as createDate3_,
        question0_.teacher_id as teacher11_3_,
        question0_.title as title3_,
        question0_.type as type3_ 
    from
        _question question0_ 
    where
        question0_.teacher_id='50100' 
    order by
        question0_.id asc

(List<Question>) session.createQuery("from Question q where q.teacher.id='"+teacherId+"' order by q.id asc ").setFirstResult(pagePos)
.setMaxResutl(pageSize).list();
