Matisse, Consider loading the FunctX library module into Sedna so that it can be used in your ad-hoc queries going forward.
Check out "2.5.5 Managing Modules" in the Sedna Documentation: http://www.sedna.org/progguide/ProgGuidesu8.html#x14-570002.5.5 On the Sedna terminal you could load the FunctX library module with a command like: LOAD MODULE "functx-1.0-doc-2007-01.xq" Once the library module is loaded into Sedna, it will remain there (even if you restart the Database). Now you will be able to use and re-use functions contained within this library module in all your ad-hoc queries going forward. Consider the following ad-hoc XQuery expression (or MainModule): ----------------- import module namespace functx = "http://www.functx.com";; functx:reverse-string("apple") ----------------- Regards, Charles > If I wish to use a user defined function in an XQuery (for example, any of > the functions from http://www.xqueryfunctions.com/) the only option I see > is to include the function definition in the query I pass to sedna.
