[ http://issues.apache.org/jira/browse/DERBY-688?page=all ]
Bryan Pendleton updated DERBY-688:
----------------------------------
Derby Info: (was: [Patch Available])
Committed d688_phase3_v1_code.patch and d688_phase3_v1_tests.patch
to subversion as revision 429847. Committed the two patches together per
Army's recommendation to commit these patches as a unit to avoid test diffs.
Clearing the patch available flag because all the pending patches have now been
committed.
Thanks for all the hard work on this, Army!

> As of DERBY-334, Derby has some very basic support for XML that consists of
> an XML datatype and three operators (XMLPARSE, XMLSERIALIZE, and XMLEXISTS).
> I would like to enhance this existing functionality and, by doing so, help to
> move Derby incrementally toward a more usable and more complete XPath/XQuery
> solution (with emphasis on "incrementally").
> I have attached to this issue a document describing the particular changes
> that I am looking to make. At a high level, they consist of:
> 1) Making it easier to use the XML operators and datatype from within JDBC
> (ex. by implicit parsing/serialization of XML values).
> 2) Adding a new operator, XMLQUERY, to allow a user to retrieve the results
> of an XPath expression (instead of just determining whether or not the
> expression evaluates to an empty sequence, which is what XMLEXISTS does).
> 3) Making changes to the existing operators to line them up with the SQL/XML
> 2005 specification, and also to take steps toward my eventual hope of having
> support for XQuery (as opposed to just XPath) in Derby.
> If anyone has time and interest enough to look at the document and provide
> feedback, that'd be great...
