Error Code: 1055. 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

I was trying to query a complicated sql query with joins, groups, etc and after upgrading mySQL the group by stopped working.

In order to fix issue I had to open mySQL and on the database I had to run the following query:

SET GLOBAL sql_mode = '';
