与setMaxResults（）在MSSQL

问题这是我的DAO类我的方法和它的作品与setMaxResults（）在MSSQL

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

，但是当我把setMaxResults（）我得到这个SQL巨大的错误，说一些关于在缺少参数声明

假设您为'setMaxResults（int maxResults）'添加一个金额' 设置要检索的最大行数。 –

我知道@RajithPemabandu这太奇怪了，我只放100 – Krismorte

添加您的persistence.xml和jdbc驱动程序版本 – jklee
