Selecting the second row of a table using rownum

Question

I have tried the below query:

select empno from (
                   select empno 
                     from emp
                    order by sal desc
               


        

Answer 1

For nth row using rownum in oracle:

select * from TEST WHERE ROWNUM<=n
MINUS
select * from TEST WHERE ROWNUM<=(n-1);

Example for second row :

select * from TEST WHERE ROWNUM<=2
MINUS
select * from TEST WHERE ROWNUM<=1;
