Hi all,
I'm trying to compile a query to avoid Oracle limit of 1000 in IN():
def chunks(l, n):
""" Yield successive n-sized chunks from l. """
for i in xrange(0, len(l), n):
yield l[i:i+n]
qry=session.query(Azienda).fiter(Azienda.c.cap=='1111')
val=[1,3,3,4,3,23,2,4,5,6,7,8,9,90,34,2]
for jj in list(chunks(val, 5)):
qry = qry.filter(sa.or_(Azienda.c.id.in_( jj )))
I expected a query like this one:
SELECT * FROM azienda
WHERE cap = '1111'
AND (
azienda.id IN (%(id_1)s, %(id_2)s, %(id_3)s, %(id_4)s,
%(id_5)s)
OR azienda.id IN (%(id_6)s, %(id_7)s, %(id_8)s, %(id_9)s,
%(id_10)s)
OR azienda.id IN (%(id_11)s, %(id_12)s, %(id_13)s, %(id_14)s, %(id_15)s)
OR azienda.id IN (%(id_16)s)
)
instead I got this one:
SELECT * FROM azienda
WHERE azienda.cap = %(cap)s
AND azienda.id IN (%(id_1)s, %(id_2)s, %(id_3)s, %(id_4)s,
%(id_5)s)
AND azienda.id IN (%(id_6)s, %(id_7)s, %(id_8)s, %(id_9)s,
%(id_10)s)
AND azienda.id IN (%(id_11)s, %(id_12)s, %(id_13)s, %(id_14)s,
%(id_15)s)
AND azienda.id IN (%(id_16)s)
How can I do this in the right way?
thanks for your help.
