Question

I have 2 tables:

usStateCities:

And usstatescentroids:

SELECT state,COUNT(*) AS  count  FROM usStateCities  GROUP BY state

Gives the number of cities in each state

SELECT *
FROM (SELECT state, COUNT(*)  AS count FROM  usstatecities ) AS a,
usstatescentroids b
WHERE a.state = b.state
GROUP BY state

Only gives one state and total number of cities in US
I want to find the number of cities in each state and the coordinates (lon,lat) of the centroid of each state.

CORRECTION I have change State to state. I cut and pasted older statements.

Answer 1

SELECT a.state, a.count, b.lon, b.lat 
FROM (SELECT State, COUNT(*) AS count FROM usStateCities GROUP BY State) a
LEFT JOIN usstatescentroids b ON b.state = a.State
