SELECTサブクエリのSUMを結合し、NULLSを持つ行を結合する

Question

データベースから請求書情報を引き出し、4つの異なる広告申込情報を合計して月別にグループ化するクエリを実行しています。このクエリは、JOINの3つのテーブル：CustomerAccount,InvoiceおよびInvoiceDetailを含む。クエリを実行すると正しい情報が得られますが、各列が1つの値を持つ4つの行に分割され、残りはNULLです。それらの行がすべて1つの行に表示されるように行を結合するにはどうすればよいですか？私がでてる

| Account# | Branch | Department | Date | Name | Delvry | Storage | Ret/Ref | Shredding 
| 1000  | MAIN | TAX  | 2016-01 | Acme | $50.00 | $200.00 | $124.00 | $12.75 

：私はそれは次のようになりたい

| Account# | Branch | Department | Date | Name | Delvry | Storage | Ret/Ref | Shredding 
| 1000  | MAIN | TAX  | 2016-01 | Acme | $50.00 | NULL | NULL | NULL 
| 1000  | MAIN | TAX  | 2016-01 | Acme | NULL | $200.00 | NULL | NULL 
| 1000  | MAIN | TAX  | 2016-01 | Acme | NULL | NULL | $124.00 | NULL 
| 1000  | MAIN | TAX  | 2016-01 | Acme | NULL | NULL | NULL | $12.75

取得したクエリ結果が、IntermediateTableという名前のテーブルに格納されていることを考慮してください。必要な結果を得るためのクエリは次のようになります。

SELECT Account# 
     ,Branch 
     ,Department 
     ,Date 
     ,Name 
     ,SUM(ISNULL(Delvry,0)) 
     ,SUM(ISNULL(Storage,0)) 
     ,SUM(ISNULL(Ret/Ref,0)) 
     ,SUM(ISNULL(Shredding,0)) 
FROM IntermediateTable 
GROUP BY Account# 
     ,Branch 
     ,Department 
     ,Date 
     ,Name
