mysql大小写与only_full_group_by

今天在部署一个很久之前的项目时碰到两个问题记录一下

1.数据库大小写

原环境为windows服务器，mysql默认是不区分表名大小写的，但是在linux下安装完mysql默认区分表名大小写，所以导致服务启动时工作流找不到部分表

解决方法为在/etc/my.cnf(mysql配置文件)末尾添加 lower_case_table_names=1，重启mysql

2.

项目迁移后测试一下，发现有好几个功能不能访问，后台报异常 “of SELECT list is not in GROUP BY clause and contains nonaggregated column 'patrolItemsKey.name' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by”，看sql应该是select 与group by之间的问题。

查询stackoverflow修改配置文件/etc/my.cnf 末尾添加 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
