[sql] Implement paging (skip / take) functionality with this query

I have been trying to understand a little bit about how to implement custom paging in SQL, for instance reading articles like this one.

I have the following query, which works perfectly. But I would like to implement paging with this one.

SELECT TOP x PostId FROM ( SELECT PostId, MAX (Datemade) as LastDate
 from dbForumEntry 
 group by PostId ) SubQueryAlias
 order by LastDate desc

What is it I want

I have forum posts, with related entries. I want to get the posts with the latest added entries, so I can select the recently debated posts.

Now, I want to be able to get the "top 10 to 20 recently active posts", instead of "top 10".

What have I tried

I have tried to implement the ROW functions as the one in the article, but really with no luck.

Any ideas how to implement it?

The fix is to modify your EDMX file, using the XML editor, and change the value of ProviderManifestToken from 2012 to 2008. I found that on line 7 in my EDMX file. After saving that change, the paging SQL will be generated using the “old”, SQL Server 2008 compatible syntax.

My apologies for posting an answer on this very old thread. Posting it for the people like me, I solved this issue today.

You can use nested query for pagination as follow:

Paging from 4 Row to 8 Row where CustomerId is primary key.

SELECT Top 5 * FROM Customers
WHERE Country='Germany' AND CustomerId Not in (SELECT Top 3 CustomerID FROM Customers
WHERE Country='Germany' order by city) 
order by city;

OFFSET     10 ROWS       -- skip 10 rows
FETCH NEXT 10 ROWS ONLY; -- take 10 rows

use this in the end of your select syntax. =)

In order to do this in SQL Server, you must order the query by a column, so you can specify the rows you want.

Example:

select * from table order by [some_column] 
offset 10 rows
FETCH NEXT 10 rows only

And you can't use the "TOP" keyword when doing this.

SQL 2008

Radim Köhler's answer works, but here is a shorter version:

select top 20 * from
(
select *,
ROW_NUMBER() OVER (ORDER BY columnid) AS ROW_NUM
from tablename
) x
where ROW_NUM>10
