Answer 1

I think the best way to do this is to create your own table with dates (you can also use master.dbo.spt_values, but I personally don't like that solution)

declare @Temp_Dates table (CDate datetime)
declare @Date datetime
select @Date = (select min(CDate) from temp)

while @Date <= (select max(CDate) from temp)
begin
    insert into @Temp_Dates (CDate)
    select @Date

    select @Date = dateadd(dd, 1, @Date)
end

select D.CDate, isnull(T.id, 0) as id
from @Temp_Dates as D
    left outer join temp as T on T.CDate = D.CDate

you can also use recursive solution with CTE
