Answer / rajdevar

Guys
i have executed this query in sql plus.This is correct

Select * from EMP_USER A where n-1 = (select count
(distinct (sal)) from EMP_USER B where A.sal<B.sal)

where n=3

reason for using n-1 is below:

1.We are using correlated sub query.so sal value from each
row in outer query(EMP_USER A) is compared with sal of all
the rows in EMP_USER B

eg:
ENAME SAL
----- -----
SMITH 800
KING 5000
FORD 3000

here third highest is 800.so when executing this 800 from
outer query is compared with 800,5000,3000 in inner query
which returns a count(distinct(sal) = 2

if you use n instead of n-1 you get a empty result.

Let me know if this is correct

Here is the correct query:

select ename,sal from emp e
where 3 = (select count(distinct(sal))+1 from emp
where e.sal < sal);

Answer / sudheer

Guys Few of you have submitted an optimal query.

select distinct sal from emp A where 3 = (select count(sal)
from emp B where a.sal > b.sal)

However the integer 3 will not give the third highest salary
as expected. Point should be noted that the row starts with
zero.

so the actual result will the fourth highest salary with the
above query.
