Answer 2

在没有看到您的表和当前 sql 的情况下，我只能建议：

  Select Coalesce(a.PartyId, b.PartyId) partyId, 
       Coalesce(a.PartyName, b.PartyName) partyName, 
       a.TotalMain, b.TotalSub
  From ([Put First Query SQL Inside here]) a
      Full Join ([Put Second Query SQL Inside here]) b
         On a.PartyId = b.PartyId
