Workaround for outer join with an IN operator in Oracle

Question

I am using Oracle SQL, so outer joins have the nice (+) syntax. I should warn you that I am not allowed to redesign the database; I work for a large organization.

If you really know the Oracel SQL syntax for a "proper" Oracle database, you could also do this...

SELECT p.Name,
       a.Attribute
  FROM people p,
       (SELECT PersonID,
               Attribute
          FROM attributes
              WHERE Attribute = 'Happy'
              OR Attribute = 'Grouchy') a
  WHERE p.personid = a.personid(+)

The point being that ANSI vs Oracle syntax is a ridiculous comment. Oracle supports both, you whichever is easier/better/manageable for you.
