Hi there, I’m currently doing some tests with BaseX and a mid-sized database (around 2 GB). I wonder myself why I’m not able to process this xquery-statement: dinstinct-values(//*[randnr]/name()) („Give me a list of all elements which have a child-element <randnr> and remove all double entries“) After about 10 seconds a got a „out of main memory“ error. What’s really strange about this: Processing the nodes itself with //*[randnr]/ works like a charm (but gives me a HUGE amount of text and is not really useful for me at all). My system: win7-x64, 4 GB RAM, Java 1.6.0_21 Thank you in advance, Rupert Jung _____ Rupert Jung <pagina> GmbH Gesamtherstellung wissenschaftlicher Werke Herrenberger Str. 51 D-72070 Tübingen Handelsregister Stuttgart HRB 380249 Geschäftsführer: Tobias Ott Phone: (0 70 71) 98 76-37 Fax: (0 70 71) 98 76-22 E-Mail: <mailto:rupert.jung@pagina-tuebingen.de> rupert.jung@pagina-tuebingen.de <http://www.pagina-online.de/> http://www.pagina-online.de
