I have a query like this -
UPDATE ACTION a
INNER JOIN subscriberinfo s ON a.subscriberId = s.id AND a.subscriberId=118
INNER JOIN ticket t ON t.subscriberId = s.id AND s.id=118
SET a.exceedusage = (SELECT FORMAT(((SUM(dataVolumeDownLink + dataVolumeUpLink))/1048576),2)
FROM cdr c
WHERE c.msisdn =12424474969
AND c.msisdn = s.msisdn
AND c.eventDate>t.cdrEventDate
AND c.eventDate < a.actionTakenOn)
WHERE a.remark='Reason : Data limit crossed'
AND a.exceedusage IS NULL;
I want to update action tables column, am I doing something wrong in this query?
Please explain me with an example that how to perform such kind of update,if possible.
Please, use group by where aggregate function is there:
UPDATE ACTION a
INNER JOIN subscriberinfo s ON a.subscriberId=118
INNER JOIN ticket t ON s.id=118
SET a.exceedusage = (SELECT FORMAT(((SUM(dataVolumeDownLink + dataVolumeUpLink))/1048576),2)
FROM cdr c
WHERE c.msisdn =12424474969
AND c.eventDate>t.cdrEventDate
AND c.eventDate < a.actionTakenOn group by c.msisdn )
WHERE a.remark='Reason : Data limit crossed'
AND a.exceedusage IS NULL;
