I have upgraded my system and have installed MySql 5.7.9 with php for a web application I am working on. I have a query that is dynamically created, and when run in older versions of MySQL it works fine.  Since upgrading to 5.7 I get this error:

> Expression #1 of SELECT list is not in GROUP BY clause and contains
> non-aggregated column 'support_desk.mod_users_groups.group_id' which is
> not functionally dependent on columns in GROUP BY clause; this is
> incompatible with sql_mode=only_full_group_by

Note the manual page for Mysql 5.7 on the topic of [Server SQL Modes][1].

This is the query that is giving me trouble:



    SELECT mod_users_groups.group_id AS 'value', 
           group_name AS 'text' 
    FROM mod_users_groups
    LEFT JOIN mod_users_data ON mod_users_groups.group_id = mod_users_data.group_id 
    WHERE  mod_users_groups.active = 1 
      AND mod_users_groups.department_id = 1 
      AND mod_users_groups.manage_work_orders = 1 
      AND group_name != 'root' 
      AND group_name != 'superuser' 
    GROUP BY group_name 
    HAVING COUNT(`user_id`) > 0 
    ORDER BY group_name

I don't understand `only_full_group_by` enough to figure out what I need to do to fix the query. Can I just turn off the `only_full_group_by` option, or is there something else I need to do?
