Hi Kyle, should this be NSO? This makes me so happy. I was just about to report this, so I'm glad to see the issue and a patch. I'm in a rush at the moment, but I'll make a note to come back to this to test and sign off. (I wish that there were an alternative to "SET NULL" for old_issues, but I don't think there is with our current architecture.) A library of ours got bitten by this. They moved their items to a new branch, deleted the old branch, but their issues are all for the old non-existent branch. I took a little look around and it seems like these might be the only relevant tables missing the foreign key relationship to the branches table. Once again, thanks Kyle!

Signed-off-by: Katrin Fischer <katrin.fischer.83@web.de> Please send a mail to the list asking for further feedback from the community before adding this constraint. It is obvious at first sight, but why didn't we add it years ago then? Anything to do with keeping the old branchcode in old issue records or so?

A search of git suggests it might have just been an oversight? In master kohastructure.sql we see the following for the branchcode column: `branchcode` varchar(10) default NULL, -- foreign key, linking to the branches table for the location the item was checked out However, there is no foreign key. It appears the comment was added by commit 91b5a09c6ce (Sun Aug 2011) but even then there was no foreign key there. |
