2         9
3         9
4         9
5         9
6         9         


        

Answer 1

If you main table is

#Temp(Title varchar(10),DateRange date)

You can do like something like

CREATE TABLE #ALLDATE(Date1 date)
DECLARE @startDate DATE='9/1/2013'
DECLARE @endDate DATE='9/30/2013'

insert into #ALLDATE
SELECT [Date] = DATEADD(Day,Number,@startDate) 
FROM  master..spt_values 
WHERE Type='P'
AND DATEADD(day,Number,@startDate) <= @endDate


select 'webshop',Date1 
from #ALLDATE
where Date1 not in 
        (select DateRange from #Temp where Title='webshop' and MONTH(GETDATE())=9)
