http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=1963 --- Comment #5 from Paul Poulain <paul.poulain@biblibre.com> --- mmm... before pushing, I had a doubt and checked kohastructure.

CONSTRAINT `shelfcontents_ibfk_2` FOREIGN KEY (`biblionumber`) REFERENCES `biblio` (`biblionumber`) ON DELETE CASCADE ON UPDATE CASCADE, So, Frederic, this case should not happen. Could you check your structure, and do you have an explanation. The constraint has been added by commit d6f8fde9 installer/data/mysql/kohastructure.sql (Marcel de Rooy 2011-12-08 16:10:57 +0100 2128) CONSTRAINT `shel is it possible that your database has been created before and the updatedatabase failed (because of invalid data) ? (not pushing this patch for now, needs a little bit more investigation) -- You are receiving this mail because: You are watching all bug changes.
