新版本的php / mysql在GROUP BY子句中出現匯總錯誤

Question

我的代碼出現錯誤，說“在選擇列表中無效，因為它不包含/聚集在group by子句中”。 我在“ MS SQL Server”中似乎很熟悉此錯誤。 我以前在MySQL中沒有遇到此錯誤。 當我將Php版本升級到7時出現此錯誤。以前的所有以前基於Web的程序都受到了影響。

我試圖在我的“ group by”子句中添加更多列，該錯誤消失了，但是輸出不是我所期望的。 下面的代碼是我的舊代碼。

SELECT  SUM(s.pscore) as towtal, s.pscore AS totalScore, s.cri_id, 
c.can_id, c.canid,c.can_name FROM score s INNER JOIN candidate c ON 
s.can_id = c.can_id WHERE cat_id=1 AND s.cri_id = '".$rows['cri_id']."' 
AND c.can_sex = 'Female' AND c.can_id='".$kert[$i]."'
 GROUP BY s.can_id ORDER BY s.can_id ASC LIMIT 5

當我添加GROUP BY s.can_id, s.pscore ，不會有任何錯誤，但是輸出不是我所期望的

Answer 1

轉到數據庫並在sql中運行此命令

set GLOBAL sql_mode='';

Answer 2

SET sql_mode=(SELECT REPLACE(@@sql_mode, 'ONLY_FULL_GROUP_BY', ''));

Answer 3

有效查詢的示例：

SELECT  SUM(s.pscore) as towtal
     , s.pscore AS totalScore
     , s.cri_id
     , c.can_id
     , c.canid
     , c.can_name 
  FROM score s
  JOIN candidate c 
   ON s.can_id = c.can_id 
 WHERE cat_id = 1 
   AND s.cri_id = '".$rows['cri_id']."' 
   AND c.can_sex = 'Female' 
   AND c.can_id = '".$kert[$i]."'
 GROUP 
    BY s.pscore 
     , s.cri_id
     , c.can_id
     , c.canid
     , c.can_name 
 ORDER 
    BY s.can_id ASC 
 LIMIT 5;

請注意，此查詢容易被注入
