mysql的版本

mysql> select version();
+-----------+
| version() |
+-----------+
| 8.0.12 |
+-----------+

在执行group  by时遇到报错,具体如下

mysql> select * from api_properties GROUP BY file_id order by file_id;
1055 - Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'bim.api_properties.id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

记得上次在5.7下也遇到了同样的问题 5.7的

win下修改my.ini,添加

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

重启mysql

启动失败,描述为

2019-08-27T09:22:54.827016Z 0 [ERROR] [MY-011071] [Server] D:\phpstudy_pro\COM\..\Extensions\MySQL8.0.12\\bin\mysqld.exe: Error while setting value 'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION' to 'sql_mode'

2019-08-27T09:22:54.827016Z 0 [ERROR] [MY-010119] [Server] Aborting

2019-08-27T09:22:54.828016Z 0 [Note] [MY-010120] [Server] Binlog end

NO_AUTO_CREATE_USER 在 5.7.* 的日志中提到已废除该模式,在 8.0.11 中删除了

修改设置为

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION

重启mysql,问题解决
