Of course, I suppose if a column "deletedbiblionumber" is added in
acqorders, we won't be able to make a "union all" between biblio and
deletedbiblio...
But that's not the more complex part of the problem.

Hello
Currently, when a biblio is deleted, it is moved to deletedbiblio (and
biblioitems to deletedbiblioitems).
Acquisition pages (basket.pl for example) are looking for
bibliographic information about orders only in biblio and biblioitems
table. So, if the biblio is deleted, the title cannot be found, while
it is present in database, in deletedbiblio table.
Same thing for statistics guided reports : if the biblio is deleted,
the reports are unable to get information on the document.
This is *very *annoying for us librarians, and taking into account the
deleted records would be nice for us.
So I am planning to make some patches to improve that: bug
http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=10758
Katrin Fisher has taken part to the discussion on this bug, but we are
not sure of the best way of improving Koha's behavior.
I suppose we could make a "union all" between (biblio and
deletedbiblio) and (biblio and deletedbiblio) in the subs getting
information about orders in C4::Acquisitions.
...BUT we cannot do that currently, because of the "ON DELETE SET
NULL" constraint in table aqorders for biblio.biblionumber column (the
biblionumber is deleted when the biblio is deleted...)
So, I suppose we need to change the structure of aqorders
- either by removing the foreign key from acqorders.biblionumber to
biblio.biblionumber
- or editing the constraint (I don't think it is possible)
- or by creating a new column 'deletedbiblionumber" in acqorders
I would prefer the 3d option (the "cleaner" for me, as I suppose
removing foreign key is not good for integrity of DB), but I am very
very far from being a database expert or a real developer.
So, what is your opinion on that subject?

M. Saby
