今天在学习“六天带你玩转数据库”的第五天课程表子查询的时候遇到了如下报错:暂未解决求各位大佬帮忙
ERROR 1055 (42000): Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated
column 'student.id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible
with sql_mode= only_full_group_by
看了有道的翻译感觉很迷茫
