Hi every one.

I want a collection between two times with special increment.

For example i have two times ( 08:00:00 And 16:00:00 , And also increment 00:30:00 )

I need all times between these times, by that increment, in this example it means :

{08:00:00 , 08:30:00, 09:00:00, 09:30:00, 10:00:00 , ... , , 16:00:00}

So i want a "Select" That do that.

Any suggestion please ?
Thanks in advance.

Hi Armin,
Here it is :

SQL

declare @st time
set @st = '8:0:0'

declare @ft time
set @ft = '16:0:0';

declare @interval int
set @interval = 30;

with a( gt )
as
(
select @st 
union all
select dateadd(mi, @interval , gt) sequence from a where dateadd(mi, @interval , gt)<=@ft
)
select * from a

Hope it helps.
