that is a flawed (and probably useless) metric, at least IMO.

with subversive as (
  select count(*) salcount

  from hr.salaries s
  join hr.dept d on d.deptno = s.deptno
  where s.salary > 100000

select salcount from subversive

1 row returned, lots of information.

Might be worth discussing with the auditors.

That and the near impossibility of auditing on number of rows returned.

Do they really want to an audit on this:

with a as (

   select level c1 from dual connect by level <= 1000000 ) ,
b as (

   select level c1 from dual connect by level <= 1000000 )
select a.c1, b.c1
from a, b

I see lots of false positive from cartesian joins in their future.

Probably caused by queries written by auditors.
