Subject [jira] Created: (DERBY-4832) Support for FULL OUTER JOIN
Date Wed, 06 Oct 2010 00:02:36 GMT
Support for FULL OUTER JOIN
---------------------------

                 Key: DERBY-4832
                 URL: https://issues.apache.org/jira/browse/DERBY-4832
             Project: Derby
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 10.6.1.0
            Reporter: Uriah Eisenstein


Support for FULL OUTER JOIN. Among other things, this could be useful for comparing table
contents or query results.

"A full outer join B" can of course be achieved using "(A left join B) union (B right join
A)", but the former would not only be shorter and more legible, but also possible to optimize
in certain circumstances.
