如何在mysql查询中执行此操作

Question

我有一个mysql表，其中包含有关公司的数据：id, company name, city, address, telephone。

我正在尝试编写一个查询，以获取其中有超过10家公司的城市列表。

有可能实现吗？

Answer 1

尝试

select city, count(*) as nbPerCity from tableName group by city having nbPerCity > 10;

Answer 2

select city from Table group by city having count(company_name) > 10 ;

或

select s.city from 
   (select city,count(company_name) as counted from Table group by city) as s
where s.counted > 10
