There is little mistake in Nitin the MONTHS_BETWEEN
(SYSDATE,hiredate)should be stated like this because if we
place hiredate firt the output comes in Negative, so it
gives all record.

select DEPTno,COUNT(EMPno),max(SAL)
from EMP
where (TO_CHAR(sysdate,'yyyy') - TO_CHAR(HIREDATE,'yyyy'))
< 25
GROUP BY DEPTno
having max(sal) < 20000
 
Is This Answer Correct ?    1 Yes 2 No
