             SQL code
也就是说,userid 会有很多,请问可以精简吗?
            select * from article,user where article.userid = '1' and article.userid = user.userid or article.userid = '2' and article.userid = user.userid or article.userid = '3' and article.userid = user.userid or article.userid = '4' and article.userid = user.userid or article.userid = '5' and article.userid = user.userid ORDER BY articleid DESC
