Jesse,
attached is a patch against DBIx::SearchBuilder 0.80 which performs the following:
a) removes ApplyLimits from the _DoCount query because I can’t understand why:
SELECT count(DISTINCT main.id)
FROM Tickets main
WHERE ((main.EffectiveId = main.id))
AND ((main.Type = 'ticket'))
AND ( ( ( (main.Status = 'new')OR(main.Status = 'open') )
AND ( (main.Queue = '1')
) )
LIMIT 50
the LIMIT 50 is useful in a count(*) query as its only purpose is to limit the number of rows returned, which will always be 1. It doesn't affect the result set that count() operates on. Or does it?
b) changes an oracle query into a sub select so that ApplyLimits can be easily applied
I haven’t had an opportunity to test in my Oracle environment as I haven’t got Oracle/Perl talking yet… but thought that it may be more useful out in the open. What else needs to be done to have Oracle “supported” as an RT database.
