我该如何解决组错误

Question

任何人都可以指出我在哪里搞乱查询以及如何纠正它。我越来越

错误是：

SQL Server数据库错误：因为它不是在聚合函数或GROUP BY子句中包含列“A.competitor_id”在选择列表中无效。 号线，1列无0

SELECT A.competitor_id, A.Competitor_Name,  

(((AVG(A.Final_Price_Shipping)/AVG(D.Final_Price_Shipping))*100)-100) as [Final Price Shipping Index],     
    (((AVG(A.Final_Price)/AVG(D.Final_Price))*100)-100) as [Final Price Index],     
    (((AVG(A.Regular_price)/AVG(D.Regular_price))*100)-100) as [Regular Price Index]     

from 


(SELECT A.competitor_id,C.Competitor_Name, COUNT(1) OVER (PARTITION BY A.competitor_id) as Row_Count, 
avg(Final_Price) Final_Price,avg(Final_Price_Shipping) Final_Price_Shipping, 
avg(Regular_price) as Regular_price ,SUM(A.Competitor_id) as cnt_NL 
from [Tb_Competitor_Product_Info_New] A with (nolock) 
inner join Tb_Competitor C on C.Competitor_Id=A.Competitor_ID 
where A.Competitor_id in (1) 
    group by A.Competitor_ID,C.Competitor_Name) As A, 




    (SELECT A.competitor_id, COUNT(1) OVER (PARTITION BY A.competitor_id) as Row_Count, 
avg(Final_Price) Final_Price,avg(Final_Price_Shipping) Final_Price_Shipping, 
avg(Regular_price) as Regular_price ,SUM(A.Competitor_id) as cnt_NL 
from [Tb_Competitor_Product_Info_New] A with (nolock) 
where A.Competitor_id in (2,3,4,5,6,7,8,9) 
    group by A.Competitor_ID) As D

只是添加组到您的查询的结束，也是你的A和d表已被加入我猜：

SELECT A.competitor_id, A.Competitor_Name,  

(((AVG(A.Final_Price_Shipping)/AVG(D.Final_Price_Shipping))*100)-100) 
    as [Final Price Shipping Index],     
(((AVG(A.Final_Price)/AVG(D.Final_Price))*100)-100) as [Final Price Index],     
(((AVG(A.Regular_price)/AVG(D.Regular_price))*100)-100) 
    as [Regular Price Index]     

from 
(.....) As A 
INNER JOIN (.....) As D on A.competitor_id=D.competitor_id 

GROUP BY A.competitor_id, A.Competitor_Name
