t-sql end of month insert - sql

Question

I have created two database tables named TSALESFACT and DimDate. TSALESFACT table contains the monthly sales target values. And DimTime contains the date values which begins from 01/01/2005.
CREATE TABLE [dbo].[TSalesFact](
[DateID] [smalldatetime] NULL,
[YearID] [int] NOT NULL,
[MonthID] [int] NOT NULL,
[SeasonID] [char](10) NOT NULL,
[DepartmentID] [char](10) NOT NULL,
[SalesAmount] [int] NOT NULL
)
CREATE TABLE [dbo].[dim_Date](
[ID] [int] NOT NULL,
[Date] [datetime] NOT NULL,
[Day] [char](2) NOT NULL,
[DaySuffix] [varchar](4) NOT NULL,
[DayOfWeek] [varchar](9) NOT NULL,
[DOWInMonth] [tinyint] NOT NULL,
[DayOfYear] [int] NOT NULL,
[WeekOfYear] [tinyint] NOT NULL,
[WeekOfMonth] [tinyint] NOT NULL,
[Month] [char](2) NOT NULL,
[MonthName] [varchar](9) NOT NULL,
[Quarter] [tinyint] NOT NULL,
[QuarterName] [varchar](6) NOT NULL,
[Year] [char](4) NOT NULL,
[StandardDate] [varchar](10) NULL,
[HolidayText] [varchar](50) NULL)
I would like to INSERT these sales target values into a new table named DailySalesTargets. But, the main purpose of this operation is writing the target sales to the each of end of month date. All of the date values for the relevant month will be zero. My desired resultset for this operation is like below:
How can I achieve this? Any idea?

Answer 1

I think this is what you are trying to do.
insert into [DailySalesTargets]([DateID],[YearID],[MonthID],
[SeasonID],[DepartmentID],[SalesAmount])
select d.[Date],d.[Year],d.[Month]
,dptSeason.[SeasonID],dptSeason.[DepartmentID]
,case when EOMONTH(d.[Date])=s.[DateID] then s.[SalesAmount] else 0 end as [SalesAmount]
from [dbo].[dim_Date] d
cross join (select distinct [DepartmentID],[SeasonID] from [dbo].[TSalesFact]) dptSeason
left join [dbo].[TSalesFact] s on d.[Date] = s.[DateID]
and s.[DepartmentID]=dptSeason.[DepartmentID]
and s.[SeasonID]=dptSeason.[SeasonID]
