Question

SELECT a.lead_id, c.state_name AS COL1DATA, count( c.state_name ) AS leadcount, (

SELECT count( won_loss ) AS wonlosscount
FROM lead_status
WHERE (won_loss = 'loss')
AND lead_id = a.lead_id
) AS losscount
FROM lead AS a
JOIN states AS c ON a.state_id = c.states_id
GROUP BY c.state_name
ORDER BY losscount DESC
