I believe that the outer join operation was not part of the prior sql
standard, sql-89?, but is part of the sql-92 standard. However, Oracle
saw the need for the operation and has had the outer join operation at
least since ver 7.0, if not prior to this (approx 1994/5), and has
retained their syntax which I find much easier to understand rather
than adopt the sql-92 standard. Oracle could adopt the new syntax in
the future, but hopefully would support the old syntax for a version or
two.
