Hi Simon,
Sorry, my bad.
I follow your tips to modify my program. It works.

from sqlalchemy import create_engine
from sqlalchemy import Table, Column, Integer, String, MetaData,
ForeignKey, \
DateTime
from sqlalchemy.dialects.oracle import NUMBE
Thank you. That makes sense.

OK well her
Awesome thank you.
So even though the Table object is attached to the metadata that was bound
to the engine that uses a mysql connection, I have to explicitly set the
dialect and compile when printing out the literal sql.
When I execute, is this handled seamlessly by the engine? Or do I need to
the easiest way is to use Python logging directly, where you can specify
configurations specific to individual loggers:
import logging
logger = logging.getLogger("sqlalchemy.engine")
handler = logging.handlers.FileHandler("somefile.log")
handler.setFormatter(logging.Formatter('%(asctime)s - %(n

ALL_UPPERCASE like that, that means you're dealing with a case-sensitive name.
Typically, names should be all lower case, indicating "case insensitive",
which is easier to deal with. Seems like there might be mor
OK, if you want to stick with hybrids, you can define your own
"SomeClass.myattribute == someobject" behavior by creating your own comparator,
see the docs at
http://docs.sqlalchemy.org/en/rel_0_8/orm/extensions/hybrid.html#building-custom-comparators
.

"concat" is a function that's specific to MySQL. So if you create an
expression against contains() without any specification that MySQL is in use,
you get a LIKE.
When the construct is compiled against the MySQL dialect, same as if it is
invoked by an engine that's associated with MySQL, you g
Can't seem to find any reference to anyone else having this issue, so it
must be something I'm doing incorrectly. In Mysql, the contains operator
doesnt seem to be translated properly by the dialect.
Docs state the following:
contains(other, **kwargs)¶
Implement the ‘contains’ operator.
I tested on python 3.3.0 exactly so you might want to check that something is
strange with your python 3.3.0 environment.

I did some more testing and it appears to be Python 3.3.0 only.
Indeed the exact same code with exactly the same SQLAlchemy version works
on Python 3.3.1 but not in Python 3.3.0.

Hi all,
I wonder if I can log all [and only] SQL statements made to the database
(using echo=True), instead of sending the output of my script | program
to a file.
Cheers,
Richard.

I'm not sure I understand the question, but given the reference
Thank you Mike!
In fact, that's not my actual model - it is a little more complex than
that (specially the @setter), that's why my curiosity about using
hybrids and the possibility to query against an object.
Best regards,
Richard.

Starting with the Wiki article on implementing views:
http://www.sqlalchemy.org/trac/wiki/UsageRecipes/Views
Is it possible to map Table instances back to classes defined through
declarative_base()? I'm using SQLAlchemy 0.7.1.
Thanks.

Hi all,
i'm trying to avoid to do the expensive autoload every time i access a
table. I found this question
http://stackoverflow.com/questions/11785457/sqlalchemy-autoloaded-orm-persistence
. If i try to do the same i get errors.
When i query (select) the Table created using unpickled metadata
