Hi Mukesh ,

Please find the below query for 3 rd highest mark from table.

    TOP 1 mark
FROM
    (SELECT DISTINCT TOP 3 mark FROM mark ORDER BY mark DESC) a ORDER BY mark

Hi Arul,

Your query gives the desired but can you please explain that why you use 'a' with second order by clause

Thanks in advance

Here 'a' is alias name for sub query

Solution 1

Use 2 queries

This gets you the top 3 salaries!

SQL

Select top 3 * from Table order by salary

Wrap that in a second query

SQL

Select top 1 *
From (Select top 3 * from Table order by salary)
order by salary desc

There is a more complex solution using Row_Number but the above will do the job.
