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
Lets edit my.cnf
sudo nano /etc/mysql/my.cnf
and add the following lines to it, save and exit nano….
[mysqld] sql_mode = STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
Lets restart mysql
sudo service mysql restart
It should work! 😉
