mysql5.7执行sql语句报错：In aggregated query without GROUP BY, expression #1 of SELECT list contains nonaggregated column 'yunva_changke.u.user_id'; this is incompatible with sql_mode=only_full_group_by

1.方法1，需要重启mysql服务

编辑/etc/my.cnf文件，加入如下参数，重启mysql
sql_mode = "STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION,NO_ZERO_DATE,NO_ZERO_IN_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER"

2.方法2，不需要重启mysql服务

可以看到模式为only_full_group_by
mysql>show variables like '%sql_mode';

mysql> show session variables like '%sql_mode%';
mysql> show global variables like '%sql_mode%';

使当前会话失效
mysql> set global sql_mode='';
mysql> set session sql_mode='';
