Hi,
I would like to get a report on analytical records created in koha.
The below is the query I tried, but getting a blank output. Iam very new to sql reports. I tried looking in the sql reports library, but could not get any.
SELECT biblio.biblionumber, biblio.title, biblio.author,
ExtractValue(bi.marcxml,'//datafield[@tag="773"]/subfield[@code="0"]') AS hostrecordnumber FROM biblio LEFT JOIN biblioitems ON (biblio.biblionumber=biblioitems.biblionumber) where ExtractValue(bi.marcxml,'//datafield[@tag="773"]/subfield[@code="0"]') is not null
