[Koha] SQL help - Retrieve itemnumbers based on local subject keyword

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!
