Hi everyone
I'm trying to produce a list of itemnumbers for a list of bibliographic records
with biblionumbers where subfield $9 in the 100 tag is in a list of authids for
authorities with the value "Jesuit" in 373$a (where trying to populate a
particular ccode with a set of items that we know will be relevant for that
ccode).
I have the following SQL query which SEEMS to run but brings up no results
(even though I know that we have authority records with 373$aJesuit linked from
bibliographic records with items attached):
----
SELECT i.itemnumber, b.title, b.author
FROM items i
LEFT JOIN biblio b ON b.biblionumber = i.biblionumber
WHERE i.biblionumber IN
(SELECT biblionumber
FROM biblio_metadata
WHERE ExtractValue(metadata, '//datafield[tag=100]/subfield[@code="9"]') IN
(SELECT authid
FROM auth_header
WHERE ExtractValue(marcxml,
'//datafield[@tag="373"]/subfield[@code="a"]') LIKE "Jesuit%"))
----
Can anyone spot where I've gone wrong? Or perhaps point me to an easier way of
doing this?
With kind regards from the Dalton McCaughey Library Team
