mysql安装参考教程：https://blog.csdn.net/qq_37350706/article/details/81707862

安装完毕后

执行sql语句 SELECT * FROM court_info GROUP BY second_court_name HAVING COUNT(second_court_name) > 1 

报错

[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

网上有好多教程，都试了一遍，结果发现大部分没有用。

依次执行这三个 sql语句，执行完毕切记   不要重启MySQL服务。不要重启MySQL服务。不要重启MySQL服务。

set session sql_mode=‘STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION‘;

set global sql_mode=‘STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION‘;

SELECT version(),@@SESSION.sql_mode,@@GLOBAL.sql_mode;
