A Database Error Occurred

Error Number: 1055

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

SELECT `district_id`, `district` FROM `tbl_gram_panchayat` GROUP BY `district`
