MSSQL上的setMaxResults（）问题

标签： java sql sql-server jpa

这是我的DAO课程中的方法及其作品

@Override
    @SuppressWarnings("unchecked")
    public List<Arquivo> listar() {
        try {
            Query query = entityManager.createQuery("from Arquivo");
            return query.getResultList();
        } catch (Exception ex) {
            ex.printStackTrace();
            return null;
        }
    }

但是当我放入setMaxResults（）时，我得到了这个SQL巨大错误，说明了声明中缺少参数的内容

这是一个知道错误或我搞砸了的错误？
