Pascal Matrix - Wishes Come True

Years ago I made a wish in my blog that an analytic function should work in a recursive query. My approach to generate Pascal Matrix seems to work with Oracle 19c database.

with n (u) as (
select 1 from dual
union all
select n.u+1 
  from n
 where n.u < 8
), q as (
select n.u v, m.u w 
  from n, n m 
), r (v,w,s,d,e) as (
select v,w, v,w,sum(w)over(order by w)
  from q
 where v = 1
union all
select q.v,q.w
      ,r.d
      ,r.e
      ,sum(r.e)over(order by r.w)
  from r 
 inner join q 
    on r.w=q.w and r.v+1=q.v
)
select v,w,s
  from r
;
