What do you mean by a model? If you are talking about an instance of a
mapped class, you could try something like this (untested):
def model_to_dict(instance):
model_dict = {}
for propname in instance.mapper.props:
model_dict[propname] = getattr(instance, propname)
return
Hi,
How can I place some initialization code for each connection in the pool?
Currently I do something like this:
engine.execute(SET collation_connection=utf8_general_ci)
engine.execute(SET names utf8)
engine.execute(SET character_set_client=utf8)
engine.execute(SET
Hi,
The mssql database does not provide a Time or a Date type, but
only datetime and smalldatetime.
In SQLAlchemy, the smalldatetime is used to implement the generic type
Date, but the Time type is not implemented.
Is there a particular reason for that ? could it inherit the DateTime
type, with
Hi Christophe,
No particular reason, just no-one has needed it yet, and the unit tests
don't cover it.
If you want to have a go at a patch, that'd be great. Otherwise I'll
take a look at this in the next few days.

Hi,
I am migrating an Access database to MSSQL server. I have coded up basic
Access support for SQLAlchemy, which I'll be commiting to the 0.4 branch
shortly.
Using autocode, I now have a set of SQLAlchemy table definitions. My
question is: what's a good way to move all the data across?
Hi Paul,
Thanks, I will give it a try. Stay tuned :-)

Hi,
Is there any special condition for the unittests to run on mssql ?
A few... you really need to be running on Windows and using PyODBC. And
then append ?text_as_varchar=1 to your DBURI.
Looking at your command line, it looks like you're running from Unix.
You can use PyMSSQL from Unix,

Hi,
I'm in the same process, and very interested in the answer !
One idea I had is to define an universal dump format, (based for
example on pytables), which could be used to backup and restore datas
from/to various databases.
If this way is a good one and a good implementation proposed, it
Hey,
I believe there is a common approach to the situation, but I just dont
know it.
Let say, I have some tables created in the DB using SQLAlchemy. Then I
modify Python code, which describes the table (add a column, remove
another column,...). What is the common way to handle this situation?

I need to do a cumulative select on postgres, and I got it to work
with some extreme SQL query, but I was wondering if it could be done
more easily without having to drop to SQL but with SQLAlchemy
statements.
Let's say I have a table with stock transactions like this:

Of course db modification is hard. It cant be done completely

theres multiple levels of issues with this.
one is, its not very clean to move objects between databases using
sessions. to do so, you have to remove the _instance_key of the
object and save it into the other session:
f = Foo()
sess1.save(f)
sess1.flush()
sess1.expunge(f)
