解决MySql查询语句报Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggre异常的问题

今天上午在公司启动项目的时候，获取一个列表的时候项目报错，内容如下：

Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'kypj-gate.t1.id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

明明是相同的项目在同事的电脑上就没问题，在网上查了一下原来是MySql版本的问题，我的MySql数据库版本是5.7.23，在5.7以上的版本实现了对功能依赖的检测，MySql默认启用了only_full_group_by SQL模式，可以试试在Navicat里面输入查询语句

select @@global.sql_mode;

得到的结果如下，

ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

照理说只要将结果中的ONLY_FULL_GROUP_BY去掉就可以，试着在Navicat里执行

set @@global.sql_mode = 'ONLY_FULL_GROUP_BY,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服务，再进入Navicat执行select @@global.sql_mode发现刚才的set语句并没有生效，

进入MySql安装路径下，打开my.ini文件，在文件的最末尾加上

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

这样一句，再重启MySql服务，发现Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggre异常的问题已经解决
