MySQL 8.0 incompatible with sql_mode=only_full_group_by问题解决

1、问题

 [Err] 1055 - Expression #1 of ORDER BY clause is not 
in GROUP BY clause and contains nonaggregated column 'yysc.rjscid'
 which is not functionally dependent on columns in GROUP BY clause; 
this is incompatible with sql_mode=only_full_group_by

2、 解决办法

2.1、暂时关闭

1. 先执行 select @@sql_mode 将值查询出来，然后将结果中的ONLY_FULL_GROUP_BY去掉
2. set @@SESSION.sql_mode='去掉ONLY_FULL_GROUP_BY的@@sql_mode值';

2.2、永久解决

1. linux下使用vim 打开mysql /etc/my.cnf（windows是安装目录下的my.ini）文件，加上以下配置，然后重启

sql_mode=select @@sql_mode查出sql_mode以后去掉ONLY_FULL_GROUP_BY的值
