I find this on an Oracle Technical Forum :
- SQL 92 is a standard with 3 levels: entrey level, intermediate level and a
third level I - can't remember (sorry...)
-
- As far as I know, Oracle is SQL 92 entry level compliant.
- INNER JOIN, OUTER JOIN, LEFT JOIN etc belong to SQL 92
- intermediate level sintax and, therefore, will not work on Oracle.

So I haven't any solution.... Can I hope about a future implementation of
Oracle outer join style ?
