[Koha] A more complete report on lost documents

Hi Vanda,

You need to connect to the biblioitems table which holds the MARC record in
its "marcxml" field, then use the SQL ExtractValue
<https://mariadb.com/kb/en/library/extractvalue/> function to pull out
these specific MARC fields. This process is necessary because not every
single MARC tag is in its own database field, you have to get most of the
data out of the field that storess the full record. So a report like this
should accomplish what you want:

SELECT i.itemnumber, b.title, b.author, i.itemcallnumber,
       i.barcode, v.lib,
       ExtractValue(bi.marcxml,
'//datafield[@tag="205"]/subfield[@code="a"]') as Edition,
       ExtractValue(bi.marcxml,
'//datafield[@tag="210"]/subfield[@code="c"]') as Publisher,
       ExtractValue(bi.marcxml,
'//datafield[@tag="210"]/subfield[@code="d"]') as Date,
FROM items i
LEFT JOIN biblio b ON (i.biblionumber=b.biblionumber)
LEFT JOIN biblioitems bi ON (i.biblioitemnumber=bi.biblioitemnumber)
LEFT JOIN authorised_values v ON (i.itemlost=v.authorised_value)
WHERE i.itemlost != 0 AND v.category='LOST'

The three ExtractValue lines pull out the fields you specified while the
one additional join adds the biblioitems table to the query.

Note that, in newer Koha versions starting with 17.05 the MARCXML record is
stored in the biblio_metadata
<http://schema.koha-community.org/17_05/tables/biblio_metadata.html> table
and so the report would look just slightly different.



Best,
