[Koha] Reporting help

[Gunilla Jensen]

Hello all

NIWA Library are combining branch collections around New Zealand into one centralised in Wellington.  For deselection purposes I'm trying to create a report, so I can see what titles we have got duplicate items in Wellington and at other branches.  However, I'm not having much success with the SQL below.  I can't get the AND operator to work (e.g. WHERE holdingbranch = 'WELLINGTON' AND holdingbranch = 'CHRISTCH').  Instead I use IN(X,Y) but this operator uses 'OR' as default so I get all titles held both in Wellington and in Christchurch instead of just the titles that are held in both places.  Can anyone help me with this?

SELECT
  biblio.title,
  items.itemcallnumber,
  items.holdingbranch,
  items.homebranch,
  items.barcode
FROM items
LEFT JOIN biblio ON items.biblionumber=biblio.biblionumber
WHERE holdingbranch IN('WELLINGTON', 'CHRISTCH')
ORDER BY biblio.title

Thank you,
Gunilla
