How do I print just 5 pages only based on this query below. It renders sometimes a full month or even 4 days when i try the following dates and disregards the actual date range. The query is linked to Jasper and passes a date range as parameters

to_date('16032020','DDMMYYYY') - to_date('20032020','DDMMYYYY')
to_date('23032020','DDMMYYYY') - to_date('27032020','DDMMYYYY')
to_date('30032020','DDMMYYYY') - to_date('03042020','DDMMYYYY')
to_date('06042020','DDMMYYYY') - to_date('10042020','DDMMYYYY')



Jasper Parameter[^]

Actual Query
select e.employee_id,
       e.initials || ' ' || regexp_replace(e.surname, '\([^()]*\)', '') farm_manager,
       r.research_station_id,
       r.name,
       dr.attendance_date attendance_date
  from research_station r
  join employees e
    on (e.employee_id = r.farm_manager)
 cross join (select ($P{Date_from} + rownum - 1) attendance_date
               from dual
             connect by level <= ($P{Date_from} - sysdate + 1)) dr
  join employee_jobs ej
    on (e.employee_id = ej.employee_id)
 where r.research_station_id = $P{Research_Station_id}


What I have tried:

Test Query
select e.employee_id,
       e.initials || ' ' || regexp_replace(e.surname, '\([^()]*\)', '') farm_manager,
       r.research_station_id,
       r.name,
       dr.attendance_date attendance_date
  from research_station r
  join employees e on (e.employee_id = r.farm_manager)
 cross join (select (to_date('16032020','DDMMYYYY') + rownum - 1) attendance_date from dual 
 connect by level <= to_date('20032020','DDMMYYYY') - sysdate + 1) dr
  join employee_jobs ej on (e.employee_id = ej.employee_id)
 where r.research_station_id = 2;

Normally you limit the number of rows by using OFFSET FETCH NEXT.

If you have an older version of oracle you need to use Rownum.

What version is your Oracle?
