I have this working query..
patients.recordid AS patientid,
CONCAT(personal.lastname, ', ', personal.firstname) AS name,
SUM(charge) + SUM(debit) - SUM(credit) - SUM(payment) AS balance
LEFT OUTER JOIN bills ON ( bills.parentid = claims.recordid )
LEFT OUTER JOIN procedures ON ( procedures.parentid = bills.recordid )
LEFT OUTER JOIN ledger ON ( ledger.parentid = ledger.recordid )
LEFT JOIN episodeofcare ON ( claims.parentid = episodeofcare.recordid )
LEFT JOIN patients ON ( episodeofcare.parentid = patients.recordid )
LEFT JOIN personal ON ( personal.recordid = patients.parentid )
GROUP BY claims.recordid
I would like to know if it is possible to further split the results of this query using procedures.dateofservice field, which is a unix timestamp. I would like to get 4 sum results for each claim, one for 0-30 days old, one for 31-60 days, one for 61-90 and finally a result for 91+ days. I know how to do this with 4 queries and then merge the results, but I'm curious if anyone knows if and how this could be done in one query.
EDIT: The last 3 joins are only to get to the patient name. The fields that are being summed up are on the ledger table.
