It has been rumored that ORACLE supports outer join and
"it was as easy as adding a plus sign '+'
to the relation that you knew might not have a qualifying tuple". 

First can anyone provide me with a example of how ORACLE employs this, and
second, are there any other languages or proposals for languages which
support outer join.  I am specifically interested in SQL-like languages.

Thanks for your help.
