Hi, we have analytical entries created for conference papers purchased in our library. We generated a report using the below query. But, unable to get the report the way I need. I wanted a separator between the subject entries that are repeated. But the separator is not getting added and all the subjects for a particular biblio record are coming without separator. We are using koha 16.05 SELECT biblioitems.biblionumber, ExtractValue(marcxml, '//datafield[@tag="088"]/subfield[@code="a"]') AS "Reportno", ExtractValue(marcxml, '//datafield[@tag="245"]/subfield[@code="a"]') AS "title", ExtractValue(marcxml, '//datafield[@tag="773"]/subfield[@code="a"]') AS "main_entry", ExtractValue(marcxml, '//datafield[@tag="773"]/subfield[@code="t"]') AS "main_entry_title", ExtractValue(marcxml, '//datafield[@tag="773"]/subfield[@code="o"]') AS "barcode", GROUP_CONCAT(ExtractValue(marcxml, '//datafield[@tag="650"]/subfield[@code="a"]') SEPARATOR '||') AS "Subject" FROM biblioitems LEFT JOIN biblio on (biblioitems.biblionumber=biblio.biblionumber) where biblioitems.itemtype='CON' Group by ExtractValue(marcxml, '//datafield[@tag="773"]/subfield[@code="t"]') Could you please let me know where iam going wrong. -- Regards T.
