How to find n'th highest value of a column?

Question

Is there a command akin to:

• 2nd highest salary from tbl_salary or

• 4th highest salary from tbl_salary ?

I've seen:

select salary
from tbl_salary t
where &n = (
    select count(salary) 
    from(
        select distinct salary
        from tbl_salary
    )where t.salary<=salary
);

How does this it works?

Are there other simple ways to get result?

Answer 1

select * from employee order by salary desc limit 1,1

Description : limit x,y

• x: The row offset from which you want to start displaying records. For nth record it will be n-1.
• y: The number of records you want to display. (Always 1 in this case)
