Hi,
A very simple question...
Context:
* I only need to retrieve values from a table
* I've a mapper object for the table
Question:
In a performance point a view which is the more suitable method:
- mappers = session.query(User).filter_by(name='ed').all()
or
- results =

Hi,
we've got some function-based indices we currently create using plain
text()-calls, like this:
CREATE UNIQUE INDEX
users_lower_email_index
ON
user_db.users (lower(email));
This works, but it would be nice to stay in the SA-world even with these

yes but pool_recycle is documented as a number of seconds, and a

Hi everyone ,
I have the following setup (snipped):
in_table = Table('in', metadata,
Column('id', Integer, primary_key=True),
Column('pA', String(6), ForeignKey('p.id'),
nullable=False),
Column('pB', String(6), ForeignKey('p.id'),
i found some discrepancies which may or may not be a bug.
When a many2many implicit assoc via secondary_table is setup with
view_only=True:
a) proploader.remote_side contains only the primaryjoin item (which
is probably ok, i dont know what it's used for), so i have to dig

So
for the record, if anyone wants doing such stuff:
there is a many to one reference A.b to B. one day it becomes
bitemporal, i.e. an association A.b to B via A2B table, which
contains other columns that cannot be invented by default values
(timestamps, disabled, etc). Hence, the association
below is ext.declarative.py's doc:
class Person(Base):
__tablename__ = 'people'
id = Column(Integer, primary_key=True)
discriminator = Column(String(50))
__mapper_args__ = {'polymorphic_on': discriminator}
class Engineer(Person):
__tablename__ =
all Column objects have to be on the base class if you're using single
table inheritance. declarative joins the Table and class definitions
together, and the base class has to represent the Table completely.
