title: Oracle - Script to find all foreign key dependencies in tree format?
body: <p>I need some script that return all foreign key dependencies in a tree format.</p>
  <p>I've found this one, but isn't tree format:</p>
  <pre><code>SELECT c.owner, c.table_name, c.constraint_name, level
  FROM dba_constraints r, dba_constraints c
  WHERE r.owner = c.r_owner
  AND r.constraint_name = c.r_constraint_name
  START WITH r.owner = 'OWNER_HERE' AND r.table_name = 'TABLE_HERE'
  CONNECT BY NOCYCLE r.owner = PRIOR c.owner
  AND r.table_name = PRIOR c.table_name
  ORDER BY level;
  </code></pre>
  <p>Is there some way to return it in tree format?</p>
