Dear BaseX folks, I'm having trouble understanding the subtleties of the WRITEBACK option. I found this issue report that seems to describe my case as well but it refers to a rather old baseX version. https://github.com/BaseXdb/basex/issues/848
As I understand it the WRITEBACK option will only work for files directly read from disk and not for those that have been added to a database at time of creation. I have created my database with a input path that already held all the xmls I needed to import: Resource Properties Input Path: /home/enea/tmp/AF PHR extraction ALL DATA Input Size: 74 MB Timestamp: 2016-12-19T08:45:34.841Z Encoding: UTF-8 CHOP: true
Does the above still apply to baseX 8.2.3? If the issue has been addressed can you describe how the current implementation works? Is the only workaround to this explicitly calling EXPORT after all the update/insertion/deletion queries to see the modifications reflected in the original files on disk?
Thanks for your help, Enea
Hi Enea,
WRITEBACK still applies only to those documents who are read from disk. As calling db:export is pretty slow, I would currently recommend you to define a convenience XQuery function that writes files on disk before updating the database.
Hope this helps, Christian

Dear Christian, we will use the explicit write back on disk route then
Thanks for your quick help, Enea
