First of all thanks to all of you for your answers and time. Michael let me
say that I agree 100% with all you wrote and my will/wish is to work as you
wrote, but when you are inside the ORM its easy, other is if you want to
interact with the ORM from outside.
In my actual system I have more
Hi,
When wrapping a query with an enclosing query to add columns computed from
the original query's columns, I'm blatantly doing this:
order_clause_list = ClauseList(*fact_query._order_by_clause)
fact_query._order_by_clause = ClauseList()

Hello everyone,
I have a big problem that alone can not solve.
There are tens of days I try to figure out how to solve this problem.

The tables don't exist yet. The Base.metadata.create_all(engine) is to
create them.
Thanks!

I'm having difficulty determining how to correctly call an oracle package
function which returns a numeric value. I want to call this:

I tried calling that using sqlalchemy.text() but I don't understand how to

Perhaps it's relevant (though I suspect not) that the class Avalanche
actually contains:
class Avalanche(Base):
events = relationship(Event,
secondary=Avalanche_Event_Association)
This is what prevents us from writing the classes in the following
order in the database definition .py
create_all() only can determine the order of tables if you use ForeignKey and
ForeignKeyConstraint objects correctly on the source Table objects and/or
declarative classes.
See http://docs.sqlalchemy.org/en/rel_0_7/orm/relationships.html#many-to-many

There's an outparam() construct specifically for Oracle OUT parameters.
Here's an example:
from sqlalchemy import text, bindparam, outparam
result = \
db.execute(text('begin foo(:x_in, :x_out, :y_out, '
':z_out); end;',
Joining to ClassA.b does not include an automatic upgrade of ClassB to also

SQLAlchemy can't quite do yet unless you hardwired a with_polymorphic onto

Thanks! I don't quite follow the statement about fully mapped

your name Avalanche_Event_Association with CamelCase made me think it was
mapped class, but this is not the case as you have it as a Table.

Well, one of the worst things that can happen in programming has
happened: It now works, and I don't know why _ I didn't change
anything that I know of, and I definitely didn't change the

hope everything stays that way.

What makes it worse, however, is that adding the autocommit execution
option or explicitly starting and stopping a transaction
did you call Session.commit() ? otherwise you're still in an open transaction,
assuming default settings.
Session.execute() is not the same as engine.execute(), where the latter is
autocommitting (assuming you also called execution_options(autocommit=True) for
