Hi All,

I have posted salaries of employees as follows...

EMPNO YEAR EARNINGS
101 1995 120000
102 1998 430000
101 1998 300000
102 1995 180000

My requirement is i need to found the top 20 EARNING employees list. The query will be similar to the following ...
SELECT EMPNO,SUM(EARNINGS) FROm EAR-EMP GROUP BY EMPNO;
( But it needs to display top 20 of the above result)

Thanks,
Reddy.

Hi Reddy,

Try this query ...First I am retrieving the 20th top most earning from the table & then by comparing to that we can extract desired result.

Code:
SELECT EMPNO, SUM(EARNINGS) FROM EAR-EMP GROUP BY EMPNO HAVING EARNINGS >= (SELECT EARNINGS FROM EAR-EMP A where N = ( SELECT COUNT(*) FROM EAR-EMP B WHERE A.EARNINGS < B.EARNINGS ));


Let me know, whether it works for you.... I hope well...

Regards,

Priyesh.
