A Database Error Occurred

Error Number: 1055

Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'siga_palopo_2021.a.ID' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

SELECT `a`.`ID`, `a`.`Tahun`, SUM(a.Col_01) as JumData FROM `tbl_08_kolom` as `a` WHERE `a`.`id_tabel` = 'gikqag' GROUP BY `a`.`Tahun` ORDER BY `a`.`Tahun` DESC
