Hi Philippe, I remember we’ve fixed a bug like this 2, 3 years ago. BaseX 9.2.1 is pretty old now; do you have a chance to upgrade to BaseX 10.4 or at least BaseX 9.6.4?
I guess the problem should disappear if you run OPTIMIZE ALL or db:optimize(..., true()) and switch to the new version. Hope this helps, cordiales salutations, Christian On Tue, Dec 13, 2022 at 11:04 AM Philippe Pons <philippe.p...@college-de-france.fr> wrote: > > Hi all, > > I tried to replace a database in the BaseX Database Administration (dba).
