创建一个存储过程   P3，列出Northwind库中的products表中UnitsOnOrder最高的五种商品的相关信息。(用游标做)

------解决方案--------------------
select top 5 UnitsOnOrder, *
from products
order by UnitsOnOrder desc

--用top 5，如下

select top 5 UnitsOnOrder, *
from products
order by UnitsOnOrder desc


--或者如下：

set rowcount 5

select UnitsOnOrder, *
from products
order by UnitsOnOrder desc
------解决方案--------------------
--能用一条SQL实现的，为什么要用游标，舍近求远？


--用top 5，如下

select top 5 UnitsOnOrder, *
from products
order by UnitsOnOrder desc


--或者如下：

set rowcount 5

select UnitsOnOrder, *
from products
order by UnitsOnOrder desc
