MySQL查詢返回無效條款錯誤

Question

我有一個查詢：

SELECT 
    f.name as f_name, 
    f.address as f_address, 
    f.business as f_business, 
    f.web as f_web, 
    f.id_service as f_id_service, 
    f.id_city as f_id_city, 
    f.id_firm as f_id_firm, 
    f.phone as f_phone, 
    p.name as p_name 
FROM Firm f 
    left join Price p on p.id_service=f.id_service 
    AND p.id_city=f.id_city AND p.id_firm=f.id_firm 
WHERE 
    p.id_city='73041' AND 
    p.include='1' AND 
    p.blocked='0' AND 
    f.blocked='0'AND 
    p.id_group='44' AND 
    p.id_subgroup='369' 
Group by 
    f.name 
ORDER by 
    f.name ASC 

我得到以下錯誤：

Msg 8120, Level 16, State 1, Line 4 
Column 'Firm.address' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause. 

爲什麼我得到這個，我該如何解決？

你應該考慮給你的問題一個更好的標題..

您不能訪問，這不是在GROUP BY在選擇列（您可能必須把他們像MIN聚合函數（... ）或MAX（...））。

我不確定爲什麼你在查詢中有GROUP BY，因爲你沒有做任何聚合？

您可能想要一起刪除GROUP BY。 您可能希望將所有列都放在GROUP BY中。 或者您可能希望刪除該組，並在SQL中的SELECT（刪除GROUP BY將爲每行提供一個結果）後添加一個DISTINCT子句。

我的猜測是，你希望像這樣的SQL：

SELECT 
    f.name as f_name, 
    f.address as f_address, 
    f.business as f_business, 
    f.web as f_web, 
    f.id_service as f_id_service, 
    f.id_city as f_id_city, 
    f.id_firm as f_id_firm, 
    f.phone as f_phone, 
    p.name as p_name, 
    SUM(p.SOMEKIND_OF_COLUMN) as sumOfPrice 
FROM Firm f 
    left join Price p on p.id_service=f.id_service 
     AND p.id_city=f.id_city AND p.id_firm=f.id_firm 
WHERE p.id_city='73041' AND p.include='1' AND p.blocked='0' AND f.blocked='0' 
    AND p.id_group='44' AND p.id_subgroup='369' 
Group by 
    f.name, 
    f.address, 
    f.business , 
    f.web, 
    f.id_service , 
    f.id_city , 
    f.id_firm , 
    f.phone , 
    p.name 
ORDER by f.name ASC
