A Database Error Occurred

Error Number: 1055

Expression #6 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'k8951989_naja.td.id_detail' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

select * from t_gallery as tg inner join t_gallery_detail as td on (td.id_gallery=tg.id_gallery) group by tg.id_gallery order by tg.id_gallery desc limit 6
