[last reply was a mistake]

@Dinesh

Using ROW_NUMBER() as in the article does not use the normal ORDER BY, that ORDER BY is part of the ROW_NUMBER syntax.

There is a way to do it without even that, but it is not very efficient. Bascially, use MAX() and WHERE <.

For example, to find the third highest id:

SELECT MAX(id) FROM mytab WHERE id < (SELECT MAX(id) FROM mytab WHERE id < (SELECT MAX(id) FROM mytab))

This can be done with a join as well.

@Dinesh

Yes. one way is ROW_NUMBER()

Hi All,

Is it possible that……..

Find Nth Highest Record from Database Table without using “TOP” and “ORDER BY”???

By: Hellock

Hellock — Wed, 28 Oct 2009 01:37:31 +0000

Am I too late?

Try this..

SELECT TOP 1 ID,Name
FROM
(SELECT TOP 6
ID, Name
FROM Table
ORDER BY ID ASC) as top6
ORDER BY ID Desc

Use DENSE_RANK() for this situation instead of ROW_NUMBER()

I just need to find the highest value row in a table. How do I do that? I assume it is going to be a simpler command.

how do we find positions of the record from a table using SQL SERVER 2000? for example

table name : employee

EMP_NAME AGE SALARY
———————————–
aaa 30 2000.00
abc 20 5000.00
bbb 40 3000.00
bbb 60 3000.00
ccc 50 4000.00
xyz 25 1000.00

there is no primary key in this table.

In this table i want to find out 3rd record. i.e.
bbb 40 3000.00

@ Jerry Hung

Can you give some more information on how row_number() will reduce performance?

Thanks in advance.

Very nice approach Nicholas.
I used the same query to gain little bit performance when we have to have the nth value out of very long list. This can give some performance boost. The inner query will give only the top results from which the top most row will be displayed

USE AdventureWorks
GO
declare @nthVal int
set @nthVal=4–the required nth value

SELECT top 1 t.*
FROM
(
SELECT top (@nthVal) e1.*,row_number() OVER (ORDER BY e1.Rate DESC) AS _Rank
FROM HumanResources.EmployeePayHistory AS e1
) AS t
order by t._Rank desc

Yes, row_number() is quite useful in these cases, and during pagination

but it is a performance drag as well, especially for pagination
imagine assigning row # to millions of records, and only need record 50~100 for page 2
