临时修改 MySQL 容器的 sql_mode

1、查询 SQL 报错：SQLSTATE[42000]: Syntax error or access violation: 1055 Expression #2 of SELECT list is not in GROUP BY clause and contains nonaggregated column ‘model.group_id’ which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by。如图1

2、在容器中连接 MySQL，执行命令：mysql -h127.0.0.1 -u用户名 -p密码。如图2

root@mysql-696746d44d-mzc8d:/# mysql -h127.0.0.1 -umysql -phqy-webtv
mysql: [Warning] Using a password on the command line interface can be insecure.

3、临时修改 MySQL 容器的 sql_mode，执行命令：set global sql_mode=’STRICT_ALL_TABLES,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION’; 。临时方案，一旦 MySQL 容器升级或者重新部署，又需要执行命令，永久方案应该是将此设置项放入基础镜像中。如图3

mysql> set global sql_mode='STRICT_ALL_TABLES,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';
Query OK, 0 rows affected (0.00 sec)

4、查询 SQL 未再报错，接口响应正常。如图4
