Hello,
As we obtain no reply for an inconsistent database, I will explain again the problem, with SQL for examples.
Currently, after using imported set of notices and using it we have the following results:
SELECT count(*)
FROM biblioitems
WHERE extractvalue(biblioitems.marcxml, '/record/datafield[@tag="700"]/subfield[@code="9"]') != ''
AND extractvalue(biblioitems.marcxml, '/record/datafield[@tag="700"]/subfield[@code="9"]') NOT IN (
SELECT authid FROM auth_header );
+----------+
| count(*) |
+----------+
| 121 |
+----------+
english-version: If I extract from MarcXML (on table biblioitems) the 700.9 (Primary Author, koha_internal_code) and search in auth_header, we currently have 121 items with no-existent 700.9 .
This is only a part of the problem: some 700.9 are existent but wrong (points to bad authority).
SELECT count(*)
FROM biblioitems, auth_header
WHERE extractvalue(biblioitems.marcxml, '/record/datafield[@tag="700"]/subfield[@code="9"]') = auth_header.authid
AND extractvalue(biblioitems.marcxml, '/record/datafield[@tag="700"]/subfield[@code="a"]') != extractvalue(auth_header.marcxml, '/record/datafield[@tag="200"]/subfield[@code="a"]');
+----------+
| count(*) |
+----------+
| 3 |
+----------+
Any suggestions ? This seems a bug (in import of notices where old koha_internal_code is not removed), but I would prefered have your opinion before submit a bugreport.
And I will like some clues to correct the inconsitences !
Thanks.
