Yes. Have you tried it?

Alternatively, You can do it in derived table too

select min(amount) from
(
select top 3 amount from grant order by amount desc
) as t

The following performs much better in large tables by preventing fetching unneeded records:

–Use a Common Table Expression
WITH CTE AS
(SELECT TOP 3 *,
RANK() OVER(ORDER BY Amount DESC) AS GrantRank
FROM [Grant] )
SELECT * FROM CTE
WHERE GrantRank = 3

Hello rstech,

Thank you so much for the reply. I think its easier to use rank() function when there is large amounts of data to be sorted out.

Thank you.

Hi Pinal and Rick,

Thanks for this nice post.

Can you please tell if there is any performance difference between the two methods shown in this post. i.e, between “Use a Common Table Expression” and “Use a Derived Table”.

Thanks.

Hello ss…
Here is a workable solution to Rick’s interview question without using the RANK() function.

/* Create a parameter that sets the position of the
business required value.
**********************************************************************/
DECLARE @nRank int;
SET @nRank = 3;

/* Use the TOP() expression with a derived table to return all
rows that meet the specified business requirement.
**********************************************************************/
SELECT TOP (1) WITH TIES *
FROM [Grant]
WHERE Amount NOT IN ( SELECT TOP (@nRank – 1) WITH TIES Amount
FROM [Grant]
ORDER BY Amount DESC )
ORDER BY Amount DESC;

Nice question and a great answer. Thanks for the pointer.
I had to use the ROW_NUMBER(), RANK() AND DENSE_RANK() functions a couple of days ago in a query that’s being used to extract data from a SQL database. Very interesting functions, and very helpful.

Pinal,

Thanks for the pointers … You have a typo:
