Hi,

Hi All – when I try and pull out subfield $u of the 856 field I always get the public note as well (i.e. $z). An example of the query I’m running:
select
biblionumber,
ExtractValue(metadata,'//datafield[@tag="245"]/subfield[@code>="a"]') AS title,
ExtractValue(metadata,'//datafield[@tag="856"]/subfield[@code>="u"]') as URL
from
biblio_metadata
where
ExtractValue(metadata,'//datafield[@tag="856"]/subfield[@code>="u"]') like '%dawsonera.com%';
This is correct isn’t it? I haven’t requested $z, so not sure why it is always in the results? Feature? Bug? Or me doing something wrong? Did you try with
[@code="u"]') ie not >= but equality?
