Your conclusion is: Xquery doesn’t get close to the mature capabilities of relational database systems when it comes to dealing with relational data! Well of course it doesn’t. It’s not designed to do that job . Data is naturally hierarchical, and XQuery is good at processing it in its hierarchical form.

Hi all, I’m after some feedback on an article I’ve posted at How to write an XQuery that is the exact equivalent of a SQL OUTER JOIN It would be great to find out if I’ve done something useful, or if I’ve managed to miss something simple that would have achieved the same result!

I am a huge fan of AutoPager add-on of Firefox. It saves a lot of time when browsing paginated websites (such as search engines, online forums, etc.) by automatically pre-loading the next page so that you never have to click Next to view the next page…( read more )

The “some” and “every” expressions can always be rewritten in terms of exists() or empty() applied to a corresponding FLWOR expression . They may provide greater expressive clarity and may perform better in some implementations, but they are functionally redundant. Regards, Michael Kay http://www.

Hallo Hans-Juergen Yes, the transformation into a for clause is more opaque and clumsy.

RE: How is satisfies different from where ?
“Balisage: The Markup Conference” (http://www.balisage.net ) is an annual peer-reviewed XML conference: how to create markup; what it means; hierarchies and overlap; modeling; taxonomies; transformation; query, searching, and retrieval; presentation and accessibility; making systems that make markup dance (or dance faster to a different tune in a smaller space). Come to lovely Montreal, Canada from August 3rd to 6th for four action-packed days of angle brackets! Here’s a baker dozen (or so) sampling from the much larger list of Balisage 2010 presentations: * gXML, a new approach to cultivating XML trees in Java * Java integration of XQuery – an information unit oriented approach * Reverse modeling for domain-driven engineering of publishing technology * Managing semantics in XML vocabularies * XML pipeline processing in the browser * Where XForms meets the glass: Bridging between data and interaction design * Schema component paths for schema analysis * A streaming XSLT processor * Multi-structured documents and the emergence of annotations vocabularies * Processing arbitrarily large XML using a persistent DOM * Automatic upconversion using XProc * Scripting documents with XQuery * XQuery design patterns * Parallel processing and your XML data Want to travel on the weekend so you can talk about angle brackets for an extra day? Then register for the pre-conference symposium on August 2nd, “XML for the Long Haul: Issues in the Long-term Preservation of XML”
