[Koha-bugs] [Bug 33905] A patron's username and cardnumber must each not be used by another patron in any permutation

https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=33905 --- Comment #25 from Martin Renvoize (ashimema) <martin.renvoize@openfifth.co.uk> --- This all looks pretty solid to me, I like the use of triggers and it's introduction here is well thought out. I did wonder a little about why we need the COALESE on NEW.borrowernumber? I've signed off to keep it moving, but the TODO stands I reckon before we can processed with QA -- You are receiving this mail because: You are the assignee for the bug.
