Question

I have an question about MYSQL If statement.
My request:

SELECT c.status, c.thumb, j.id, j.name, j.username, s.session_id, a.time, a.isactive, a.country, a.countrycode, a.city
FROM j16_users AS j 
JOIN j16_community_users AS c ON c.userid = j.id 
LEFT JOIN j16_session AS s ON s.userid = j.id 
LEFT JOIN j16_session AS s ON s.userid = j.id 
LEFT JOIN j16_x5_fastchat_users AS a ON a.userid = j.id 
WHERE j.id IN (62,66,2692)

How can I add a new column: isonline with condition to above request:

IF(a.time > DATE_SUB(NOW(), INTERVAL 1 MINUTE), "1", "0") AS isonline

Thanks!
