You can fix it buy removing the ONLY_FULL_GROUP_BY option or by rewriting your queries. From MySQL 5.7. only_full_group_by comes as default.

If in doubt check MySQL manual which has comprehensive explanation how MySQL is handling GROUP BY: https://dev.mysql.com/doc/refman/5.7/en/group-by-handling.html


To turn off ONLY_FULL_GROUP_BY check to value of the sql_mode variable.
Execute this query in your favorite MySQL client:

Edit MySQL config file my.conf . Usually in /etc/my.cnf or /etc/mysql/my.conf . If not sure, execute this command from your shell:

copy sql_mode values, remove ONLY_FULL_GROUP_BY and put this line in my.conf under [mysqld] section.

In my case it looks like this:

Restart the mysql server
