A Database Error Occurred

Error Number: 1055

Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'netprorefRev2.1.skills.skill_id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

SELECT `skill_id` as `value`, `name` as `label` FROM `skills` WHERE `status` = '1' GROUP BY `name`
