Nth highest Salary.
I need a well tuned query to find the nth highest salary from emp table.
I have one but no idea if it is tuned one.
select min(sal) from (select sal,rownum from (select sal from (select distinct sal from emp order by sal desc)) where rownum <=n) ;
You can use analytic functions.
select *
from (
select e.*, row_number() over(order by sal desc nulls last) rno
from emp e
where rno = 5 --<<-- replace 5 with N
I need a well tuned query to find the nth highest salary from emp table.This totally depends on how you have setup your database.

Doesnt the Nth high paid employee earns the Nth highest salary?
No. Multiple employees can earn same salary. Look at EMP table:

Highest salary 5000. Second highest salary is 3000. Third highest salary is 2975. Now look what NTH_VALUE returns:

Nth Highest Salary from EMP table , need explaination
I am new to the database world and hence learning queries at the initial stages. I want to retrieve the nth highest salary from the EMP table. I was not able to find out the answer by myself , so I searched on google. The following was the answer i got :
SELECT DISTINCT (a.sal) FROM EMP A WHERE &N = (SELECT COUNT (DISTINCT (b.sal)) FROM EMP B WHERE a.sal<=b.sal);
Enter value for n: 2
SAL
3700
Suppose the table contains salary in the following order :
SAL
2000
3000
3700
4000
3700
2000
So how come I will get the correct answer with the abov query ? I am not able to understand the part --- WHERE &N = (SELECT COUNT (DISTINCT (b.sal)) FROM EMP B WHERE a.sal<=b.sal);
Specially the condition WHERE a.sal<=b.sal is very confusing to me. Can anyone help me please to understand the same.user12328699 wrote:

But still if you want to understand the same.
Assuming the data is sorted in ascending order, then
1) a.sal=2000, so a.sal<=b.sal results in count as 3 (not equal to user input)
2) a.sal=3700, so a.sal<=b.sal results in count as 2 (equal to user input)
3) a.sal = 4000 , so a.sal<=b.sal results in count as 1 (not equal to user input)
Hence the answer is 3700

ABAP Query to display top 5 employees who are having highest salary
How will you write a query in abap to display top 5 emplyeee records who are having Highest Salary Among all the employees.
Please Reply...Hi Kush,
Before writing any Database Query, always keep 2 important thumb rules in your mind :
1. Keep the number of data base access small
2. Keep the amount of data transfer small.
As you mentioned the Database Table has only 100 records, you can locally buffer the Table. So, make a local buffering and then you can sort the table based on the salary.
Select *
from Table_name
into table gt_itab.
Sort gt_itab by salary descending.
Now you can read the entries one after the another based on the index.
Have a look at the following code for an efficient performance feature. Goto SE38 and have a look at the ABAP Examples.
demo_select_some_columns. Package : SABAPDEMOS
Hope this will help.
Thanks,

To find 2nd highest salary in employee table
Hi,
I want to know how to calculate the 2nd highest salaried employee details.
rownum "=" sign cannot be used i suppose and
with and without using orderby clause.
both the methods needed.
cheers,With order by
select * from
( select q.*, rownum as rn from
( select * from emp order by sal desc ) q
where rn=2
/With analytics:
select empno , sal
from ( select empno , sal
, dense_rank () over (order by sal desc) as sal_rank
from emp )
where sal_rank = 2Notice that DENSE_RANK() might give us a different result compared to RANK() and both give us a different result from the first example.
Cheers, APC -
SQL query on emp table(SCOTT Schema): Highest salary per department
From emp table of SCOTT schema. I would like to know the name, sal,the deptno he belongs of the highest paid employee from each dept.
Explaining further:
The following query only returns deptno and max(sal) of each department. I need the name of the highest paid employee from each dept along with the below result.
SQL> SELECT DEPTNO,MAX(SAL) FROM EMP GROUP BY deptno;
DEPTNO MAX(SAL)
30 2850
20 3000
10 5000It seems you want just one ename if two employees have the same highest salary. In that case you can use this construct:
SQL> select deptno
2 , max(sal)
3 , max(ename) keep (dense_rank last order by sal)
4 from emp
5 group by deptno
6 /
DEPTNO MAX(SAL) MAX(ENAME)
10 5000 KING
20 3000 SCOTT

Do not multi-post to the forums.

hi, i am kind of new to sql. i have a table with employee name and salary.
i would like to find the name of the 2nd highest salary? also i like to get the name of the 5th highest salary
here is my data
INSERT INTO er4 VALUES('john', 1000, 123);
INSERT INTO er4 VALUES('john2', 3000, 234);
INSERT INTO er4 VALUES('john3', 1000, 223);
INSERT INTO er4 VALUES('john4', 4000, 123);
INSERT INTO er4 VALUES('john5', 8000, 023);
INSERT INTO er4 VALUES('john6', 9000, 023);
INSERT INTO er4 VALUES('john7', 8000, 723);
you can see in the data that there are two employee with highest second salary. i would like to get either one but i want my query to return one row
can somebody help me write a query to get the name and salary of 2nd highest and name and salary of 5th highestHi,
Part of learning about functions is learning what they are good for, and what they are not good for.
As Justin said, MAX is not good for this task.
If you were interested in just the 1st highest salary, you possibly could use MAX like this:
SELECT *
FROM er4
WHERE salary = (
SELECT MAX (salary)
FROM er4
AND ROWNUM = 1 -- in case of a tie, pick one row arbitrarily
;But even if the goal was to find the highest salary, I would use ROW_NUMBER, like Justin did.
Why? The following scenario happens all the time in real life. The client for whom you wrote this comes back in 3 months and says: "That query you wrote for the highest salary works great! We've found it so useful, we'd like to do something similar to find the 2nd highest salary, or the 5th highest, or the top 5, or the next 5." ROW_NUMBER is flexible enough to do all these things. When you have to solve one problem, you'll save time (in the long run) if you can foresee, or just guess, what similar problems you might need to solve later, and write something for today's problem that can easily be adapted for tomorrow's potential problem.
