Sri, sorry for saying this, but your question is one of the vaguest i have seen in my stint with SSC..

There is absolutely no information about the emp table in your post, but you have thrown a frisbee to us to find something..:doze:..

You know, the amount you put to guess a solution will be the same for us too..Hmmm..

Anyways, assuming your emp table has a column called EMPID and it is a INT/BIGINT/SMALLINT column, here is how you retrive the last 5 rows

SELECT TOP 5 * FROM EMP ORDER BY EMPID DESC

Hope this helps you!

Cheers!

When posting questions, be sure to post more and detailed information in order for us to assist you faster and better.

Do you have an ID column? or any column with computed numbers in a specific order?

It could even be datetime stamps?

If you have a column like that, try:

Select top 5 * from emp

order by ?column? DESC

Note: this is not the best way to do this query, but given the limited info, this is a basic "retrieve last 5 records" query.

Heh... I dunno CC... looks like you did alright. 😉 In fact, you've probably just helped someone graduate. 😛

Hi

You can also use RowNumber, if you know the number of rows of data see
