A Database Error Occurred

Error Number: 1055

Expression #214 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'kaff2017.persons_roles.role_id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

SELECT * FROM (`entries`) LEFT OUTER JOIN `persons_roles` ON `role_entry_id` = `entry_id` LEFT OUTER JOIN `persons` ON `person_id` = `role_person_id` LEFT JOIN `program_film` ON `entry_id` = `program_film_film_id` WHERE `entry_id` = '1720' GROUP BY `entry_id`, `person_id`
