Hi all, Koha 16.05.03 on Ubuntu 14.04 LTS (package install) I need to batch modify a subset of records in our db. I have to use itemnumbers rather than barcodes to populate the list because not all of the records to be modified have a barcode. I've tried the following SQL to no avail: SELECT itemnumber FROM items WHERE (SELECT biblionumber, ExtractValue(marcxml,'//datafield[@tag="690"]/subfield[@code>="a"]') LIKE <<Enter keyword surrounded BY %>> As you can see, I need to retrieve item numbers based on a keyword query from the 690$a field (MARC21). Would someone be so kind as to lend a hand? Much appreciated! C Craig Butosi, MA, MLIS, B Mus (Hons.)
