如何在oracle中灵活显示结果？

Question

How to make my script to be flexible? I mean, if there's a new person added in the table, it would not need to do a modification in the sql script. Please help me. I really need help.

Thank you.

Here's the sql script:

select 'Data'
||','||to_char(d.dtime_day,'MM/dd/yyyy')
||','||nvl(d.total,0)
||','||nvl(r.total,0)
||','||nvl(rj.total,0)
||','||nvl(a.total,0)
from table1 d
left join(
      select trunc(t.create_time, 'DD') as ddate
            ,u.name as person1
            ,count(t.responsible_user_id) as total
      from table2 t
      left join table3 u
      on t.responsible_user_id=u.id
      where u.id in (3,35)
      and u.title like '%name'
      group by trunc(t.create_time, 'DD')
              ,u.name
 ) d on d.dtime_day = d.ddate
 left join(
      select trunc(t.create_time, 'DD') as ddate
            ,u.name as person2
            ,count(t.responsible_user_id) as total
      from table2 t
      left join table3 u
      on t.responsible_user_id=u.id
      where u.id in (4,39)
      and u.title like '%name'
      group by trunc(t.create_time, 'DD')
              ,u.name
  ) r on d.dtime_day = r.ddate
  left join(
      select trunc(t.create_time, 'DD') as ddate
            ,u.name as person3
            ,count(t.responsible_user_id) as total
      from table2 t
      left join table3 u
      on t.responsible_user_id=u.id
      where u.id in (8,59)
      and u.title like '%name'
      group by trunc(t.create_time, 'DD')
              ,u.name
 ) rj on d.dtime_day = rj.ddate
 left join(
      select trunc(t.create_time, 'DD') as ddate
            ,u.name as person4
            ,count(t.responsible_user_id) as total
      from table2 t
      left join table3 u
      on t.responsible_user_id=u.id
      where u.id in (25)
      and u.title like '%name'
      group by trunc(t.create_time, 'DD')
              ,u.name
  ) a on d.dtime_day = a.ddate
  where d.dtime_day between trunc(sysdate,'DD')-12*7 and trunc(sysdate) -1
 and trunc(d.dtime_day, 'DD')= d.dtime_day
 order by d.dtime_day;

I didn't try this but I think you can create a view from the SQL script, after that you can create a trigger which triggers before insert key and replaces the view.
it's just an idea.
