A Database Error Occurred

Error Number: 1055

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

SELECT * FROM (`ecu_systemtype`) GROUP BY `systemtype_name` ORDER BY `systemtype_name`
