Can you spot the error in code that you cannot see?
Neither can anyone else.

We have to know the code you are using, as well as the data type of the date column. If that data type is anything other than DATE, then you have a failed design, but it can probably be worked around.

if you want the number of people who joined in september 1999 then

select to_char(hiredate,'Mon/yyyy') month,count(*)
from emps
where hiredate between to_date('09011999','mmddyyyy') and last_day(to_date('09011999','mmddyyyy'));

If it is other than that, use a similar idea

Just add the appropriate GROUP BY clause.

Why attach an image? Many people are blocked from such links. Even if not it is an unnecessary inconvenience. Do you not know how to copy text from a command window and paste that text directly into you messages? If you were unaware that you can do that, then now you know and I leave it as an exercise for the student to research how to to do it. You shouldn't have to ask anyone except Google.

If hiredate can have times other than midnight then that should be:

where hiredate >= to_date('09011999','mmddyyyy')
and hiredate < last_day(to_date('09011999','mmddyyyy')) + 1

Otherwise anything after midnight on the last day will be ignored.

Agreed, I just assumed that a hire date would be a truncated date.
