[Koha] Report help

[Elaine Bradtke]

Ramiro
That's very useful, thanks. I've expanded it a little to accommodate our
date range (yes we have some old items) and changed it to say "Unknown"
rather than older, because I suspect these are questionable dates or
missing data.  Quite a few dates are missing in the 008 field. One of the
difficulties in producing reliable statistics!

SELECT
CASE SUBSTR(ExtractValue(m.marcxml,'//controlfield[@tag="008"]'),8,2)
      WHEN '19' THEN 'XX'
      WHEN '20' THEN 'XXI'
      WHEN '18' THEN 'XIX'
      WHEN '17' THEN 'XVIII'
      WHEN '16' THEN 'XVII'
      WHEN '15' THEN 'XVI'
      ElSE 'Unknown' END
   AS bibtype, count(DISTINCT biblionumber) AS bibs FROM biblioitems m
GROUP BY bibtype
