https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=10869 --- Comment #96 from Martin Renvoize <martin.renvoize@ptfs-europe.com> --- We have an ON DELETE SET NULL on the foreign key.. whilst I like keys for integrity that's wrong if we actually want to keep the link when the biblio is moved to deleted_biblios.. This needs some thought... another case where merging tables would help. We could just remove the code level key requirement in th store routine for biblionumber if it doesn't already exist in storage? -- You are receiving this mail because: You are watching all bug changes.
