解决Mysql在分类查询时报1055 - Expression

        今儿在分类查询时Mysql报错，1055 - Expression #2 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'lyhz.r.river_picture' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode

        百度时有不少都说进入mysql控制台运行语句啥的，跑了一遍都没有效果，实际解决问题用的下面这种方法，当前测试服务器Ubuntu：

    解决方法：

1.sudo vim /etc/mysql/conf.d/mysql.cnf

2.在配置文件最后一行粘贴以下语句

[mysqld]

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

3.保存退出后

        sudo service mysql restart to restart MySQL
