Help with custom OpsCenter script

All,

Perhaps someone can assist.  We are using OpsCenter 7.6  I am looking for a report that shows the amount of data, number of jobs, number of clients, storage unit used, master server name, schedule name, policy type PER policy name.   Here is my code.  Please assist as this times out.

SELECT

domain_MasterServer.networkName as [Master Server],

domain_policy.name as [Policy Name],

lookup_PolicyType.name as [Policy Type],

domain_Schedule.name as [Schedule Name],

nb_JobAttemptArchive.destStorageUnit as [Storage Unit],

SUM(domain_jobArchive.bytesWritten) as "KB",

COUNT (domain_JobArchive.endTime) as [# of Jobs],

COUNT (DISTINCT domain_jobarchive.clientid) as [# of Clients]

FROM domain_masterserver, domain_policy, domain_Schedule, domain_jobarchive, nb_jobattemptarchive, nb_jobarchive, lookup_PolicyType
