Help: How to get number of sales for a period of months in a report?

Question

I am working on a report with a table having emp_id and order_date. Given input date Begin_date (mm/yyyy) and End_date (mm/yyyy), I need to create a report that shows the number of orders have sold for each emp_id for each of the months within the input range.
Thank you in advance.

I think it should work for you.
select
   ORDERtable.emp_id,
   allmonths.xmonth,
   ORDERtable.amt
from
   (select
      ORDERtable.emp_id,
      to_char(ORDERtable.order_date,'MM/YYYY') order_month,
      sum(ORDERtable.amt) amt
    from
     ORDERtable
    group by
       ORDERtable.emp_id,
       to_char(ORDERtable.order_date,'MM/YYYY')) ORDERtable,
    (select
       to_char(add_months(trunc(:p_datefrom,'mm'),cn-1),'MM/YYYY') xmonth
     from
        (select rownum cn
           from
             dual
             connect by level <= (months_between(:p_dateto, :p_datefrom)+1))) allmonths
where
   allmonths.xmonth = ORDERtable.order_month(+)
order by
   ORDERtable.emp_id,
   allmonths.xmonth
