Hello,
I'm new to SQLAlchemy and have searched high and low for a solution to my
problem so I'm hoping someone here can help. I have a query where I need to
apply the 'order by' clause dynamically (both the column and the

everything in python is ultimately in a namespace, the names are strings, the
values are the objects.
like if you had “myapp.model” as a module, and in that module were Study and
Site, you could say:
from myapp import model
Study = getattr(model, “Study”)

I don't know if this is what you're thinking, but you can also just build a
query object in different ways if you want to
query = session.query(Study).options(
