Hi Samuel, Try this query which assumes that the 955 data is in subfield a: SELECT COUNT(biblioitems.biblioitemnumber) as '955 tag' FROM biblioitems WHERE ExtractValue(biblioitems.marcxml, '//datafield[@tag="955"]/subfield[@code="a"]') > 0 The query counts all 955 tags. It can be modified to count 955 tags in records added on a specific date or date range. As a test, you may want to first run this query which selects 5 records with the 955 tag so you can check the biblio records in cataloging: SELECT biblio.biblionumber, biblio.title, ExtractValue(biblioitems.marcxml, '//datafield[@tag="955"]/subfield[@code="a"]') as '955 tag' FROM biblioitems, biblio WHERE biblioitems.biblionumber = biblio.biblionumber AND ExtractValue(biblioitems.marcxml, '//datafield[@tag="955"]/subfield[@code="a"]') > 0 LIMIT 5 Bev On Thu, Jan 17, 2013 at 6:27 AM, Samuel Desseaux <samuel.desseaux@ecp.fr>wrote:
