Question

The following link explains how to turn a date range into a list of dates.
I used this approach and it works fine but the query is not performing (I used Maxrecursion 0 to unlimit).

Is there any other solution to get this done? (using subquery or declare table?)

Answer 1

Try

declare @datestart date = '2012-1-1',   @dateend date = '2012-10-31'

declare @days int = datediff(d,@datestart,@dateend)

select
    dateadd(d, number, @datestart)
from master..spt_values 
where type='p'
    and number<=@days

If your date range is more than 2047 days, you can extend it by self joining the table – the below will allow you up to 27 years..

select
    dateadd(d, v1.number+v2.number*2048, @datestart)
from master..spt_values v1
    cross join (select number from master..spt_values where number<5 and type='p') v2       
where type='p'
    and (v1.number+v2.number*2048)<=@days
