[sqlalchemy] UnboundExecutionError: text query with elixir
Hello, I'm trying to run the following query with elixir entities: elixir.metadata.bind = 'mysql://root:root@localhost/mutdb' elixir.metadata.bind.echo = True elixir.setup_all(True) t = text(select * from mutations) result = elixir.session.connection().execute(t) and I got: sqlalchemy.exc.UnboundExecutionError: This session is not bound to a single Engine or Connection, and no context was provided to locate a binding. I though elixir does all the initialization with setup_all(), what else is needed to run queries like this? Normal mapped queries like Mutation.query.all() work normally. thanks david -- You received this message because you are subscribed to the Google Groups sqlalchemy group.

I would have thought Elixir associates the engine with the Session, if not you may ask on their list. You can associate the contextual session (i.e. , a ScopedSession wrapper) with a bind by doing: session.configure(bind=engine) before the contextual session is first used. -- You received this message because you are subscribed to the Google Groups sqlalchemy group.

Yes, I also looked and the elixir session is an SA ScopedSession, I'll try the explicit bind. thanks david On Mon, Feb 28, 2011 at 5:58 PM, Michael Bayer mike...@zzzcomputing.comwrote: ssociates the engine wit -- You received this message because you are subscribed to the Google Groups sqlalchemy group.
