Home -> Community -> Mailing Lists -> Oracle-L -> Re: sql query
Seema:
Here's my crack at it:
select x.userid
, x.superid
, nvl(y.count, 0) as count
from mytable x
, (select a.userid
, a.superid
, count(*) as count
from mytable a
, mytable b
where a.userid=b.superid
group by a.userid, a.superid) y
where x.userid = y.userid(+)
