def connection(self, mapper, **kwargs):
returns a Connection corresponding to the given mapper.

method which performs select operations for Mapper and Query.

if you dont mind relying upon garbage collection to close connections
then you dont have to worry about closing anything. otherwise youd
need to call close() on the connection.
the closest thing to the old behavior of execute() is the _execute_raw
method on Connection:
conn = engine.connect()

I worked on this some more and found that the queries are correct as
they are. The problem is in the mapping. A Chemical Engineer is an
Engineer, who is an Employee. So the employees selectable should return

As I've been experimenting with inheritance, I think my hang ups are
largely due to my lack of understanding of how SA accomplishes it. So
