[Koha-devel] Issues table and foreign keys in general

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I have noticed some things: 1. issues table has nullable borrowernumber and itemnumber; foreign key constraints are consequently declared as "ON DELETE SET NULL ON UPDATE SET NULL" 2. That is not an isolated issue, there are many cases where foreign key field/constraints are declared like that Can anyone shed more light, that looksvery wrong to me. Thanks, Srdjan -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk2k/pcACgkQX6p/D9UE7dy2fQCfZP/QeVQSb7VNNMJvA5yYWdBj AvAAn0fRuZ1KinfIiIIWCR+EgXhmYBu8 =2WSQ -----END PGP SIGNATURE-----
