I'm not sure what the problem you are encountering is, but I wanted to make
sure to point out that the 001 field does not necessarily contain the
OCLC#, and if you want the OCLC# you should always get it from the 035,
like this:
ExtractValue(marcxml, '//datafield[@tag="035"]/subfield[@code="a" and
contains(text(), "OCoLC")]') AS 'OCLC Accession Number'.

I also noticed that in the quoted section in your e-mail 'OCLC Control
Number' is not in quotes, but should be, which may be the problem you are
encountering.

A final suggestion is that the version of MySQL you have installed may be
too old to support ExtractValue, in which case the only solution would be
to upgrade.

Regards,
Jared
