Question

H All,

I have following ResultSet generated by some 3-4 queries in T-Sql. The result looks something like this:

Month Payment
January 200
February 200
March 200
April 200
june 200
July 200
August 200
September 200
October 200
November 200
December 200

Now, depending on userdefined value, lets say 4, I need to arrange them some like this.

Month Payment
January;Febrary;March;April 200
May;June;july;August 200
…………. so on.

If the user has chosen for 3, then,

Month Payment
January;Febrary;March 200
April;May;June 200
…………. so on.

How do I do this? Any suggestions?
Thanks in Advance!!
:))

I honestly don’t know how to handle payment since you have not described it, here is a way of solving it with recusive sql

declare @t table([Month] varchar(12), Payment int)
declare @uservalue int
set  @uservalue = 3
insert @t values('January',200)
insert @t values('February', 200)
insert @t values(' March', 200)
insert @t values('April', 200)
insert @t values('May', 200)
insert @t values('June', 200)
insert @t values('July', 200)
insert @t values('August', 200)
insert @t values('September', 200)
insert @t values('October', 200)
insert @t values('November', 200)
insert @t values('December', 200)

;with a as(
select month, payment, rn = row_number() over (order by (select 1))
from @t
), b as
(
select cast(month as varchar(200)) month, payment, rn
from a where (rn - 1) % @uservalue = 0
union all
select cast(b.month +';'+ a.month as varchar(200)), a.payment, a.rn
from b join a on a.rn - 1 = b.rn and b.rn %@uservalue > 0
)
select month, payment from b where rn % @uservalue = 0
