Daniel,

Tomas's suggestion is good, but I would like to propose to switch its SELECT for using ExtractValue(marcxml, '//datafield[@tag="020"]/subfield[@code="a"]')

The reason is that the isbn column in the database contains concatenated ISBNs and the field length is limited, so the list of ISBNs could be truncated.

A good suggestion, but to be a tad pedantic, SchemaSpy has biblioitems.isbn as mediumtext, 16777215, [checkmark], null, ISBN (MARC21 020$a); I'm not sure how many you'd have to concatenate to truncate one and two thirds Mb ;=)

The SELECT assume that you are using MARC21.

In addition, you could also get invalid ISBN using the subfield z

The final query would be :

SELECT ExtractValue(marcxml, '//datafield[@tag="020"]/subfield[@code="a"]') as ISBN FROM biblioitems where ISBN <>""

Note that some lines may content more than 1 ISBN.

Cheers,

You should create a guided report for this. Do it at Reports > Create from
SQL, and paste this into the SQL field:

SELECT title, author, isbn

FROM biblio

LEFT JOIN biblioitems

ON (biblio.biblionumber=biblioitems.biblionumber)


Choose an apropriate name for the report.

Hi all,

Running into something that seems like it should be simple,
but I'm running in circles trying to figure it out -- is there
a simple (or not simple) way to export a document
containing titles, authors, and isbn numbers?

In truth, all I really need are the isbns -- stocktaking and
inventory exports don't seem to include isbn numbers
as a field. I could make a "List" and export that as csv, but
  I want ALL the isbns in my library, in which case it seems
like i'd have to add all titlesmanually to a list.

So, in short, my goal is: a document, preferably CSV,
containing all isbns in my koha library of approx 3000 items.

Any tips?

Many thanks,
Daniel
