Hi Linda,

I need to find records having a 773 field that  are missing either a
subfield "9". or a subfield "o"..
I'm at a loss of how to accomplish this. Any input would be appreciated.
Thanks in advance.

This should do the trick:

SELECT biblionumber
FROM biblioitems
WHERE marcxml RLIKE '<datafield tag="773"'
AND ExtractValue(marcxml, '//datafield[@tag="773"]/subfield[@code="9" or @code = "o"]/text()') = '';

Regards,

Galen
