How to do this in a mysql query
I have got a mysql table containing data about companies: id, company name, city, address, telephone
.
I'm trying to write a quer开发者_高级运维y for getting list of cities where there are more then 10 companies within.
Is it possible to achieve that?
Try
select city, count(*) as nbPerCity from tableName group by city having nbPerCity > 10;
select city from Table group by city having count(company_name) > 10 ;
or
select s.city from
(select city,count(company_name) as counted from Table group by city) as s
where s.counted > 10
