Bernt M. Johnsen commented on DERBY-4355:
-----------------------------------------
Well, it is an INNER JOIN, although the INNER keyword is optional. Any user
fluent enough in SQL to write an inner join without the optional keyword and
with the following ON or USING clause should know that.
> Implement CROSS JOIN

> Implement the CROSS JOIN syntax

> SELECT * FROM t1, t2;
> This should be pretty straight forward and ease the migration of SQL code to
