sql获取分组排序后数据的脚本

先上一段代码，如下所示：

select distinct 
b.OrgID,b.CompanyID,b.AreaID,b.CustChannelID,b.CustID,b.SaleTotalQty,
GETDATE() from KDS400TelSurveyCustAll_Temp  as tmp1 cross apply
(
select top 10 percent * from KDS400TelSurveyCustAll_Temp tmp2
where tmp1.OrgID=tmp2.OrgID and tmp1.CompanyID=tmp2.CompanyID
and tmp1.AreaID=tmp2.AreaID and tmp1.CustChannelID=tmp2.CustChannelID
and tmp2.CustChannelID in (1027,1028)
order by tmp2.OrgID,tmp2.CompanyID,tmp2.AreaID,tmp2.AreaType,tmp2.CustChannelID
) as b

这段代码的意思是获取取每个经销商在每个县级城市中两类客户
取各类客户的前3个月累计销量排名在前10％的客户进行调查。
