cid is actually a event identifier bound to an event and a sensor (sid)

So sensor 1 (sid 1) cid are not sensor 2 (sid 2) cid, etc..


SELECT * FROM signature WHERE sig_sid = 25568;

SELECT * FROM cid FROM event WHERE signature =  SELECT sig_id FROM
signature WHERE sig_sid = 25568 AND sid = 1;

SELECT * FROM data WHERE cid IN (SELECT cid FROM event WHERE signature
= (SELECT sig_id FROM signature WHERE sig_sid = 25568) AND sid = 1);
SELECT * FROM data WHERE cid IN (SELECT cid FROM event WHERE signature
= (SELECT sig_id FROM signature WHERE sig_sid = 25568) AND sid = 1);

Hope this helps
