先上一段代码，如下所示：

复制代码 代码如下:

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。
