Wie bekomme ich eine Gesamtsumme für jeden VersichertenCounty und Durchschnitt für jeden Mod

Question

Wie kann ich den Gesamt-Premium für jedes VersicherteCounty und Durchschnitt für ExperienceMod, SchedureMod, TerritoryMod, EffectiveMod in einer Abfrage zurückgeben?

select * 
from (SELECT Insured, 
      InsuredCounty, 
      PolicyNumber, 
      EffectiveDate, 
      PolicyType, 
      SUM(Premium) as Premium, 
      ExperienceMod, 
      ISNULL(ScheduleMod,0) as ScheduleMod, 
      TerritoryMod, 
      ISNULL(EffectiveMod,0) as EffectiveMod, 
      ROW_NUMBER() OVER (PARTITION BY Insured,PolicyNumber,Premium, TransactionType ORDER BY PolicyType DESC) as rid 
     FROM ProductionReportMetrics 
     WHERE EffectiveDate <= EOMONTH(GETDATE()) 
     AND CompanyLine = 'Arch Insurance Company' 
     AND Insured <>'Jerry''s Test' 
     AND TransactionType = 'Policy' 
     GROUP BY Insured, 
       InsuredCounty, 
       PolicyNumber, 
       PolicyType, 
       EffectiveDate, 
       experienceMod, 
       ScheduleMod, 
       TerritoryMod, 
       EffectiveMod, 
       Premium, 
       EffectiveDate, 
       TransactionType 
    ) b 
where rid = 1 
ORDER BY InsuredCounty, Premium desc, EffectiveDate 

Aktuell Ergebnis sieht wie folgt aus:
