MySQL group by報錯

項目中切換mysql數據庫後，之前正常的SQL報錯。報錯語句爲：

ERROR 1055 (42000): Expression #1 of SELECT list is not in GROUP BY clause 
and contains nonaggregated column '***' which is not 
functionally dependent on columns  in GROUP BY clause; this is 
incompatible with sql_mode=only_full_group_by

解決方法：

找到mysql配置文件my.cnf

linux使用名稱查找位置：

find / -name my.cnf

文件最後添加：

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

重啓服務，解決。

service mysql restart

 

附::my.cnf文件全部內容:

[mysqld]
bind-address=0.0.0.0
port=3306
user=mysql
basedir=/usr/local/mysql
datadir=/data/mysql
socket=/tmp/mysql.sock
log-error=/data/mysql/mysql.err
pid-file=/data/mysql/mysql.pid
#character config
character_set_server=utf8mb4
symbolic-links=0
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
