[Err] 1055 - Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated column
'information_schema.PROFILING.SEQ' which is not functionally dependent on columns in GROUP BY clause;
this is incompatible with sql_mode=only_full_group_by
----------------------------------
执行: select @@sql_mode;
查看sqlMode: ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION
把 ONLY_FULL_GROUP_BY 去掉即可。
修改配置文件: D:Program Filesmysql-8.0.12-winx64my.ini
如果没有该文件则新建, 在[mysqld] 下添加 sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION ，即去掉 ONLY_FULL_GROUP_BY ，然后重启mysql
