おかげカレンダーテーブルを持っていない場合は、動的な日付/時刻を生成し、TVFを使用することができます
Declare @Date1 date = '2016-01-01' -- These could be a query for min/max dates
Declare @Date2 date = '2016-12-31'
Select A.StartDate
,StartMonthYear = month(A.StartDate)*10000+Year(A.StartDate)
,A.EndDate
,B.QuotaAmount
,B.TeamName
From (Select StartDate=RetVal,EndDate=DateAdd(DD,-1,DateAdd(MM,1,RetVal)) From [dbo].[udf-Range-Date](@Date1,@Date2,'MM',1)) A
Join YourTable B
on A.StartDate between B.StartDate and B.EndDate
Order by TeamName,A.StartDate
