Thanks, Chris.
So, correct to say that a report like the one below would not be affected by patrons deleted via Koha?
Checkouts by Item Type SELECT items.itype AS Collection, COUNT( statistics.itemnumber ) AS Count FROM statistics LEFT JOIN items ON (statistics.itemnumber = items.itemnumber) WHERE date(statistics.datetime) between '2009-01-01' and '2009-12-31' AND statistics.type IN ('issue','renew') GROUP BY items.itype
Nope, that would work just fine, as no join to borrowers.
(Hmm ... in looking at this, maybe it needs to be revised to take into account deleted items?)
Well the left join with items, will mean you will get null rows so one of your groups will be null (grouping by items.itype). If you want to know the actual itemtypes then yeah, you will need to do a union of items and deleteditems and join to that Chris
