Subject [jira] Commented: (DERBY-39) Strange error in JOIN ON clause
Date Thu, 29 Apr 2010 06:43:55 GMT

    [ https://issues.apache.org/jira/browse/DERBY-39?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12862110#action_12862110

Andy Jefferson commented on DERBY-39:
-------------------------------------

Thx for your reply. 
Not sure I understood the "The problem ... a column in the A0 table is referenced in an ON
clause" ... you mean "LEFT OUTER JOIN ... " is making use of joining to A0 ? Looks perfectly
valid to me, joining to a FK of the primary table of the statement, and indeed works on all
other RDBMS I've used.

Where do I get hold of derby 10.6.0.0 bearing in mind it isn't yet released ? Nightly builds
?
