Well, I've started looking through my books for info on joins. The cross
join was pretty easy:
postgres=> select * from (a cross join b);
i| j|i| k
-+----+-+--
1|10.1|1|-1
2|20.2|1|-1
4| |1|-1
<snip>
which I've put into my copy of the parser.
Does anyone have a commercial installation which has good support for
SQL92 joins? I'd like to send some small test cases to verify that I
understand what the behavior should be.
Also, if anyone has worked with join syntax, outer joins especially, it
would be great to get some test case contributions...
