yeah there's some bad history with the API here, in that you can't easily pass
them all at once, but right now it's q.options(undefer('*')) for everything or
q.options(undefer('x'), undefer('y'), ...). or undefer_group() if you've
applied a group to them.

Hi,
my program tries to read data from a configurable, unknown user table.
So I came up with such a statement:
result = self.session.execute(SELECT * FROM :mytable, {mytable:
self.table})
But when I run it, I get this, what I do not understand:

Hi, I've looked up the scoped_session api documentation, but didn't find a
method to return the current number of active and/or closed sessions
residing in a scoped_session object. Is there a simple way to achieve this?

not really reading this thread since it isn't too SQLA specific but if you're

The part I am not understanding though is what does SqlAlchemy want my data
to look like to be an acceptable format.
I know how to create my models and db in SqlAlchemy and though I am a
