几个MYSQL查询,不知道对不对,

<br />
$byNid=$n['Nid']-500;<br />
$s="select nid,name,i from biao where name='$name' and i>'$i' order by nid>'$byNid' desc";<br />


已知nid是肯定大于500以上,
Nid是自增,从现在的Nid(如Nid=1000) 减去500,那就是从 Nid 500 开始到 1000 查询
i字段有3种数字,分别是  0,1,2 

以上的语句是可以得到  nid 500起到最新的nid 1000 止,
得到变量name,i大于1的排序,而且是从大到小的排序。

语法对吗?
