Erk indeed! Thanks Barton.
I have the habit of looking at 995 for items ;)
: Jonathan's use of ExtractValue is correct, but item data isn't stored in biblioitems.marcxml -- as a matter of fact, it's not stored in marc at all... it's *always* generated on the fly.
You can query against items.itype instead.

Hi Kerrie, I'd say that the following query returns what you want:
SELECT biblioitems.biblionumber, marcxml from biblioitems where ExtractValue( marcxml, '//datafield[@tag="942"]/subfield[@code="c"]' ) = "";

Hi Everyone,
I'm trying to get a report to identify which bib records in my Koha do not have anything in the 942 $c Koha Item Type marc field.
I tried to tweak a report from the report library, but it doesn't
appear
to work correctly as some of the results do have things in the 942$c field. Can anyone help me work out what I'm doing wrong?
SELECT biblio.biblionumber, SUBSTRING(biblioitems.marcxml, LOCATE('<subfield code="c">',
biblioitems.marcxml, LOCATE('<datafield tag="942"', biblioitems.marcxml)+19),
LOCATE('</subfield>', biblioitems.marcxml, LOCATE('<subfield code="c">',
biblioitems.marcxml, LOCATE('<datafield tag="942"',
biblioitems.marcxml)+19)) - LOCATE('<subfield code="c">', biblioitems.marcxml,
LOCATE('<datafield tag="942"', biblioitems.marcxml)+19)) AS itemtype
FROM biblioitems, biblio
WHERE biblioitems.biblionumber = biblio.biblionumber AND url IS NOT NULL
I'm specifically wanting a list of bib records that have nothing in
2016-08-10 14:32 GMT+01:00 Barton Chittenden <barton@bywatersolutions.com the
942$c marc field.
Any help very much appreciated. I have almost no SQL experience/knowledge!
Thank you
