I have a table with a list of cities.


I have another table with a table of listings.


How do I query the list of cities and include a column with the total number of listings for that city?


I have:


SELECT a.*,(SELECT COUNT FROM tbl_listings WHERE city=a.id) AS cnt FROM tbl_cities


Database Structure(ish)


CITIES


ID | CITY


01 | Atlanta


02 | Boston


LISTINGS (one example)


ID | CTY| DETAILS


01 | 01 | Listing 1


02 | 01 | Listing 2


DESIRED RESULT


01 | Atlanta | 345


02 | Boston | 43
