Database Error

A Database Error Occurred

Error Number: 1055

Expression #16 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'agenziavi_smastinew.tbl_course_duration.id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

SELECT *, `tbl_course`.`id` as `courseId` FROM `tbl_course` JOIN `tbl_course_duration` ON `tbl_course_duration`.`course_id`=`tbl_course`.`id` GROUP BY `tbl_course`.`id` ORDER BY `tbl_course`.`seq_id` ASC LIMIT 4
