Hi all,
I wonder why there's such difference between oracle and pg:
oracle:
(Pdb) engine.connect().execute(sql).fetchone()
select * from ruolo_permesso where cod_ruolo = 'SYSADMIN' and
cod_permesso='TIPO_FIGURA' and inserimento='1'
None
(1273, 'SYSADMIN', 'TIPO_FIGURA', 1, 1, 1, 1)
(Pdb)

From your earlier post:

Here's Engine.dispose (line 1152, engine/base.py)

reliable for an UPDATE or DELETE statement.Feel free to consult on
the cx_oracle mailing list for why it might return 0 for a one-row
SELECT statement - my guess would be that no rows were fetched from
the server.
I drastically sped up my inserts by precomputing any defaults on a
column and passing them explicitly instead of calculating them on each
insert. For example, each row had a timestamp and the timestamp was
being calculated on each insert for each row. Since I was inserting
them all at the same

Oh... i didn't explain myself... I mean that it's already empty at the
first cycle of the loop...
It would be normal to not enter the loop if you haven't yet opened any
connections, as connections are opened on demand. Make sure your program
issues at least one query during this test. If you
you shouldnt be using order_by on your mapper(). thats a really old
option in any case.if you need it to be there, say
query.order_by(None).statement to cancel the order_by in each separate
part of the union. however it would be even easier if you just said
query.union(q1, q2) here
youre going to want to set order_by like this too instead of the
string 'any'
class Anything(Base):
__tablename__ = 'anything'
id = Column(Integer, primary_key=True)
any = Column(String)
something_id = Column(Integer, ForeignKey('something.id'))

Hi,
Is there a way to update a large number of objects without looping
through each one, using SA's ORM?
E.g.
I want to achieve the following:
for o in session.query(MyClass).filter_by(prop='some value'):
o.prop = 'new value'
session.update(o)
Without fetching and saving each object
the update() method on Query accomplishes this. Make sure you read
the docstring for it which describes some various behaviors you'll
want to be aware of.
alternatively, any SQL expression, like table.update(), UPDATE
table can be issued within the ORM's transaction using
14 matches
