mysql-ERROR 1140 (42000)错误解决办法
查询语句:
select student.stu_name,max(score.number) from student inner join score on student.stu_id = score.student_id inner join course on score.course_id = course.cou_id inner join teacher on course.teacher_id = teacher.tea_id where teacher.tea_name ="杨艳";
报错:
ERROR 1055 (42000): Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column ‘oldboy.student.stu_name‘ which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
解决办法:
退出mysql
vim /etc/my.ini
在[mysqld]项下添加如下代码:
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
:wq保存退出
service mysqld restart 重启mysqld服务
问题解决!
