I run three HP minicomputers and two Sun Ultra 3000 all with 
Oracle 7.3 and one with Oracle 8.0 .

Send it to me.

Subject: [HACKERS] JOIN syntax. Examples?


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...
                     - Tom
