Check the query and you will get the desired result as you expected.

select max(DEPT_NO), count(*) from < Table Name > ;

SSR...

Try this query...

Code:
SELECT COUNT(EMP_NO) AS EMPCOUNT, DEPT_NO   
FROM DB2ID.TABLENAME
GROUP BY DEPT_NO                         
ORDER BY EMPCOUNT DESC FETCH FIRST ROW ONLY;

hi priyesh,

Is there any way by which we could used the max function for this as this would be a simple one, but i did various trials but no use.

Regards
