求一条sql查询语句？
我现在有一个表：
order_ID:     订单编号
BookID：　图书编号　　　这两个是主键
BookSellprice　：图书单价
Bookamount：　　图书数量

现在要取出相同图书既BookID相同的，图书数量总和最大的前10个BookID  
这是我在做一本书上的例子，求销售排行，请各位帮忙想一想？？

------解决方案--------------------
select top 10 sum(Bookamount) as qty,BookID from yourtablename group by BookID order by qty desc
------解决方案--------------------
求数量排行榜：
select top 10 sum(Bookamount) as BookTotal ,BookID from 表名 group by BookID order by BookTotal desc

求销售价格排行榜
select top 10 BookID,sum(BookSellprice*Bookamount) as BookTotal from 表名 group by BookID order by BookTotal desc
