Order by COUNT per value

Question

I have a table which stores IDs and the city where the store is located.

I want to list all the stores starting with the stores that are in the city where there are

Answer 1

This one calculates the count in a separate query, joins it and orders by that count (SQL-Fiddle):

SELECT c.id, c.city
FROM cities c
JOIN ( SELECT city, COUNT(*) AS cnt
       FROM cities
       GROUP BY city
     ) c2 ON ( c2.city = c.city )
ORDER BY c2.cnt DESC;
