Create and Populate Date Dimension for AdventureWorksDW2012

Question

Does anybody have scripts for DimDate for AdventureWorksDW 2012 or 2014?
If I generate Schemas and data, it takes several megabytes. I have requirement that this should be done with script to save space. I have also need to extend the script with local calender requirements.

If you mean to populate the DimDate table with range of dates, try the following:
Create table #dates (
[date] date not null
declare @d date
set @d ='2010-01-03'; --- change this to the start date that you want
while @d < '2017-01-01' --- change this to the end date that you want
begin
set @d= DATEADD(DAY,1,@d)
insert into #dates (date) values (@d)
end
select date,
[YEAR] = datepart(year, date),
[MONTH No.] = datepart(month, date),
[MONTH] = case datepart(month, date) when 1 then '01 January'
when 2 then '02 February'
when 3 then '03 March'
when 4 then '04 April'
when 5 then '05 May'
when 6 then '06 June'
when 7 then '07 July'
when 8 then '08 August'
when 9 then '09 September'
when 10 then '10 October'
when 11 then '11 November'
when 12 then '12 December'
end,
[day]= datepart( day, date),
[weekday] = case datepart(weekday, date) when 1 then 'Sunday'
when 2 then 'Monday'
when 3 then 'Tuesday'
when 4 then 'Wednesday'
when 5 then 'Thursday'
when 6 then 'Friday'
when 7 then 'Saturday'
end
from #dates
