Hi Mike, thanks to reply my question.
In my case the extract function is unuseful because it needs a datetime
to extract parts of it
but I don't have a datetime but a codified date.
I need to manage a string which is a personal code with info about name,
birthday, birth place and gender.
It looks like in sqlalchemy = 0.9.9 that a insert from cte doesn't get
rendered properly.
Code:
from sqlalchemy import *
table = Table(my_table, MetaData(),
Column(id, Integer, primary_key=True),
Column(name, String(30)),
)
c = table.select().cte(c)
query = c.select()
insert =
I've found some rather unexpected behavior when using
joinedload(...).load_only

The ex.description attribute is loaded on the first result, but not on the
second, even though all the data is part of the result.
It looks like the data is discarded when the

Hello,
Sorry I couldnt find info about in google neither in the documentation,
I have a model structure like this one:

Would you be able to use a TypeDecorator?
http://docs.sqlalchemy.org/en/latest/core/custom_types.html#sqlalchemy.types.TypeDecorator
That will allow you to define a function for handling how sqlalchemy
inserts and accesses the data from sql.

The problem is a behavioral quirk. I'm not sure if this is a regression or
not, but I've seen it brought up recently...
IIRC:
The join creates a matrix result (many rows), but `first()` only pulls the
first item from the result.
Calling 'one()' will pull all the results, but raise an error
I was afraid that was the only solution, but how to delete and insert new
row with the relationships of the old one?

OK so the ORM doesn't support an object changing into a new class in
place. You have to emit the UPDATE that you want, and

it doesn't seem like you have to. your Person refers to
accomodation.id, and you aren't deleting from that table, only UPDATEing
the type.
