A Database Error Occurred

Error Number: 1055

Expression #2 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'credware_lokpratinidhi_live.tbl_jilahaparishadh.dist_photo' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

SELECT `dist`, `dist_photo` FROM `tbl_jilahaparishadh` WHERE `status` = 'Approved' GROUP BY `dist`
