MySQL this is incompatible with sql_mode=only_full_group_by having count

查看当前mysql的sql_mode配置：

select @@GLOBAL.sql_mode

就是这里限制了，解决办法如下：

vim /etc/my.cnf

在mysqld下面加上这个：

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION

再次查询：

查询有重复的值：

SELECT id,count(*) as counts FROM `apps` GROUP by name HAVING count(id)>1
