A B updated DERBY-3023:
-----------------------
Fix Version/s: 10.3.2.2
Tinderbox runs on trunk ran for several days with no apparent fallout from the
changes for this issue, so I ported back to 10.3 with a simple merge command:
svn merge -r 612503:612504
https://svn.apache.org/repos/asf/db/derby/code/trunk
I ran derbyall and suites.All with ibm142 and there were no new failures. So I
committed with svn # 614046:
URL: http://svn.apache.org/viewvc?rev=614046&view=rev
Updating fix-in to reflect the fact that this is now in 10.3.

> Project: Derby
> Issue Type: Bug
> Components: SQL
> Affects Versions: 10.1.2.1, 10.2.2.0, 10.3.1.4
> Environment: Windows XP, Java 1.4.2
> Reporter: Stefan Cordes
> Assignee: A B
> Fix For: 10.3.2.2, 10.4.0.0

> We have a complex SQL joining 11 Tables via INNER JOIN and OUTER JOIN.
> These SQLs were tested against an z/OS DB2 Version 8.
> After moving to our local platform with Derby we found out the resultsets
> returned by the SQLs were too less.
> I tested our "old style" SQL which results in 889 rows.
> Our new style SQL expected to give similar rows but gives *0*.
> After some work we found a workaround: first place all the "INNER JOIN"s in
> the SQL and then the "OUTER JOIN"s.
