Hi all, No issues here, just following up in case someone is looking at this thread in the future. I updated the database using the sql statement below, and it deleted most of the 852 datafields. I thought all was well but a week or so later found a record that still had some 852 datafields in it. Upon investigation I found a number of records - around 400, and all of them had multiple 852 datafields - at least two per record. I did some experimentation and the sql statement below only works on those records where there is a single 852 datafield. I tried some variations and found that if I ran this one it would remove the first 852 datafield: update biblioitems set marcxml = UpdateXML(marcxml, '//datafield[@tag="852"][1]', ''); I did a backup, ran the sql statement above several times until it returned 0 records changed (17 in fact, as I had one record with 16 852 datafields). Each time it ran it stripped off the leading 852 datafield. I then ran this one to check for any leftovers: SELECT ExtractValue (marcxml ,'//datafield[@tag="852"]/*') FROM biblioitems WHERE marcxml RLIKE '<datafield tag="852"'; It returned zero results. Ran touch_all_biblios.pl Zebra indexes rebuilt that night as part of our regular cron job. All looks good. - Doug -----Original Message----- From: Galen Charlton [mailto:gmc@esilibrary.com] Sent: Tuesday, August 28, 2012 3:42 PM To: Doug Dearden Subject: Re: [Koha] Fwd: Re: Barcode info and maybe SQL/MARCXML help needed Hi, No, whitespace between datafield elements is irrelevant as far as Koha's parsing of the MARCXML records is concerned.

Hi Galen,
I ran the sql command against my test DB to delete the 852 tag limiting it to one record. It takes out the 852 datafield but leaves behind some blank space - example below. Is this going to matter? - Thanks, Doug
<datafield tag="700" ind1=" " ind2=" "> <subfield code="a">Hymes, Dell, editor.</subfield> </datafield>
<datafield tag="942" ind1=" " ind2=" "> <subfield code="c">BK</subfield> </datafield>

Hi,

Unless you had changed your MARC frameworks to use the 852 field for item data rather than the 952, if the 852s are from your previous system, I'd suggest that you actually *delete* them. A bib export from Koha will include the item data in 952 fields if you need them for record interchange or union catalog purposes, and getting rid of the legacy 852s avoids the risk of confusing staff about the state of an item record.
And you can delete the 852 fields in two steps (or three, counting the backup you should make first :) ). First, run the following SQL update:
update biblioitems set marcxml = UpdateXML(marcxml, '//datafield[@tag="852"]', '');
Then run touch_all_biblios.pl, which will (in addition to signalling that the bibs should be reindexed) synchronize biblioitems.marc with biblioitems.marcxml.

Galen
