MySql 中与 only_full_group_by 相关的错误答案

【问题标题】：Error related to only_full_group_by in MySqlMySql 中与 only_full_group_by 相关的错误
【发布时间】：2019-09-21 15:45:16
【问题描述】：

我创建了只给出了 only_full_group_by 错误的查询。我想更改查询未设置 sql_mode=only_full_group_by

#1055 - SELECT 列表的表达式 #4 不在 GROUP BY 子句中，并且包含在功能上不依赖于 GROUP BY 子句中的列的非聚合列“hrdk.s.item_stock_id”；这与 sql_mode=only_full_group_by# 不兼容

这是给我带来麻烦的查询：

SELECT `s`.`department_id`, `s`.`category_id`, `s`.`item_id`, `s`.`item_stock_id`, `s`.`tunch`, `cat`.`category_name`, `im`.`item_name`, `im`.`stock_method`, `cat`.`category_group_id`, SUM(s.grwt) AS grwt, SUM(s.ntwt) AS ntwt, sum(s.less) AS less, SUM(s.fine) AS fine
FROM `item_stock` `s`  
LEFT JOIN `item_master` `im` ON `im`.`item_id` = `s`.`item_id`  
LEFT JOIN `account` `pm` ON `pm`.`account_id` = `s`.`department_id`  
LEFT JOIN `category` `cat` ON `cat`.`category_id` = `s`.`category_id`  
WHERE (im.stock_method = 1 AND (`s`.`grwt` =0 OR `s`.`grwt` !=0)   
   OR (`im`.`stock_method` = 2 AND `s`.`grwt` != 0))  
   AND s.department_id IN(26,27,28,29,30,31,32,59)   
   AND `s`.`grwt` !=0  
   AND `s`.`department_id` = '26'   
GROUP BY `s`.`category_id`, `s`.`item_id`, if(`im`.`stock_method` = 1, `s`.`tunch`, "")  
ORDER BY `s`.`item_stock_id` DESC

如果您需要更多信息，请告诉我。

【解决方案1】：

您必须在group by 中添加所有非聚合列

SELECT s.department_id, s.category_id, s.item_id, s.item_stock_id, s.tunch, cat.category_name, im.item_name, im.stock_method, cat.category_group_id, SUM(s.grwt) AS grwt, SUM(s.ntwt) AS ntwt, sum(s.less) AS less, SUM(s.fine) AS fine 
FROM item_stock s LEFT JOIN item_master im ON im.item_id = s.item_id 
LEFT JOIN account pm ON pm.account_id = s.department_id 
LEFT JOIN category cat ON cat.category_id = s.category_id 
WHERE (im.stock_method = 1 AND (s.grwt =0 OR s.grwt !=0) OR (im.stock_method = 2 AND s.grwt != 0))AND s.department_id IN(26,27,28,29,30,31,32,59) AND s.grwt !=0 AND s.department_id = '26' 
GROUP BY s.department_id, s.category_id, s.item_id, s.item_stock_id, s.tunch, cat.category_name, im.item_name, im.stock_method, cat.category_group_id
ORDER BY s.item_stock_id DESC
