This makes sure that the FK is always "ON DELETE SET NULL". To test: * Before applying this path * sudo koha-mysql kohadev * show create table reserves; CONSTRAINT `reserves_ibfk_ig` FOREIGN KEY (`item_group_id`) REFERENCES `item_groups` (`item_group_id`) ON DELETE CASCADE ON UPDATE CASCADE * Apply patch * Run database update * Check database again: CONSTRAINT `reserves_ibfk_ig` FOREIGN KEY (`item_group_id`) REFERENCES `item_groups` (`item_group_id`) ON DELETE SET NULL ON UPDATE CASCADE * reset_all (create a new database) * Check database again: CONSTRAINT `reserves_ibfk_ig` FOREIGN KEY (`item_group_id`) REFERENCES `item_groups` (`item_group_id`) ON DELETE SET NULL ON UPDATE CASCADE -- You are receiving this mail because: You are the assignee for the bug.
