sql_mode=only_full_group_by错误

1.错误现象

   
        INSERT
        INTO
        tb_product_sell_daily(product_id,shop_id,create_time,total)
        (
        SELECT
        product_id,shop_id,date_format(create_time,'%Y-%m-%d'),count(product_id) AS total FROM
        tb_user_product_map
        WHERE
        date_format(create_time,'%Y-%m-%d') = date_sub(curdate(),interval 1 day)
        GROUP BY product_id)
    

语句：

INSERT INTO tb_product_sell_daily(product_id,shop_id,create_time,total)
 ( SELECT product_id,shop_id,date_format(create_time,'%Y-%m-%d'),count(product_id) AS total 
FROM tb_user_product_map 
WHERE date_format(create_time,'%Y-%m-%d') = date_sub(curdate(),interval 1 day) 
GROUP BY product_id) 

SELECT list is not in GROUP BY clause and contains nonaggregated column 'o2o.tb_user_product_map.shop_id' which is not functionally
dependent on columns in GROUP BY clause; this is incompatible with
sql_mode=only_full_group_by

2.错误原因

MySQL 5.7.5及以上功能依赖检测功能。如果启用了ONLY_FULL_GROUP_BY SQL模式（默认情况下），MySQL将拒绝选择列表，HAVING条件或ORDER BY列表的查询引用在GROUP BY子句中既未命名的非集合列，也不在功能上依赖于它们。（5.7.5之前，MySQL没有检测到功能依赖关系，默认情况下不启用ONLY_FULL_GROUP_BY。有关5.7.5之前的行为的说明，请参见“MySQL 5.6参考手册”。）以下解决方案并不是最终解决方案，只是屏蔽了报错，但问题依然存在。

3.临时性解决方法

mysql> select @@global.sql_mode;
+-----------------------------------------------------------------------------------------------------------------------+
| @@global.sql_mode                                                                                                     |
+-----------------------------------------------------------------------------------------------------------------------+
| ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION |
+-----------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)

在/etc/my.cnf中设置（去掉ONLY_FULL_GROUP_BY）

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION

然后重启数据库
