Use a join to get the city name
Use grouping to group the most common cities
select a.*, b.* from table1 a inner join table2 b on a.id = b.id [where clause]
group by a.id
Would need a little more data about the structure of the tables to give a more complete answer

Hi there,
I am trying to do a tricky task with PHP and MySQl 4.0.x
There are 3 content tables where each of them contains a city_id and there is a 4th table which holds the city_id and the acording city_name
Now I would like to find out the most used city names.
For example:
members pictures reports 3 4 3 2 9 8 9 8 8
So the most used city_ids are 8 3 9
To find this out would be a chelenging task, but to merge them with the city name is even more difficult
I am working on this quite a while now and cant find a way. Maybe someone of you guys could give me a smart push.
Thank you for any help,
Merlin
