I've procedure which takes 25 records at a time(thanks to everyone here who helped me on it). The procedure is for a bulletin board I'm coding. The procedure is used to get 25 topics at a time. The 25 record thing is a paging(I didn't want to do it with ASP). The script takes topics, for example 1-25 or 26-50 etc.

The script has a order command. The problem is, the order command sorts after it has taken the 25 records. What I want is, the procedure should first sort by date and time columns and then take the defined 25 records. How should I modify it?

The sql code is here:


create procedure proc_GetTopics
@forumNumber int, @LOWER_LIMIT int=0, @UPPER_LIMIT int=25
as
set nocount on

declare @sql nvarchar(3000)

set @sql='
select dbo.[TOPICS].T_ID, 
dbo.[TOPICS].T_Topic,
dbo.[TOPICS].T_PostDate,
dbo.[TOPICS].T_LastReplyDate,
dbo.[TOPICS].T_LastReplyTime
from dbo.[TOPICS]
where 
T_ID not in
(select top '+convert(varchar, @LOWER_LIMIT)+' T_ID 
	from dbo.[TOPICS] 
	where T_ForumNumber='+convert(varchar, @forumNumber)+' 
	order by T_ID)
and T_ID in
(select top '+convert(varchar, @UPPER_LIMIT)+' T_ID 
	from dbo.[TOPICS] 
	where T_ForumNumber='+convert(varchar, @forumNumber)+' 
	order by T_ID)
and T_ForumNumber='+convert(varchar, @forumNumber)+'
order by T_LastReplyDate desc, T_LastReplyTime desc, T_PostDate desc'

exec dbo.sp_executesql @sql

go
