create a mapping to retrieve the employees who are getting salary greater than average salary?..

Answer / maxy

I think it's better to have a null check here in the exp
before aggregating.
If salary is Null for any employee it will not be consider
while caculating the avg.
ex-
epm sal
e1 10
e2 20
e3
e4 30

Though there are four employee avg will be 20.
