Suppose I wish to do something like:
Session.query(Files.original_name, MSPResponse.*
because MSPResponse table has so many fields, and I want to get them
all. How do I do this given that I am also picking field(s) from other
tables ? Thanks RVince

Thanks to all you guys. Really. I didn't think I would be able to do
this! RVince

. I am quite certain this is becuase I am using a
ResultProxy object. How can I output such an object inthe mako files,
or alternatively, how might i convert a ResultProxy objectsuch that I
can output it in a mako file? Thanks! RVince

Michael,
Right, thats a better idea -- I am working with snippets of other
people's code here. However, I still have the original problem of
going from a ResultProxy object to output in a mako file which is a
chasm I cannnot seem to bridge! RVInce

LOL,I'm going backwards here, and taking far too long to get something
so very simple done (there's a genuine lack of documentation here I
think -- the only way to manage to learn much of this is by trial and
error). Rather than trying to do this with straight SQL statements I
will go plan B here
I have about half a dozen PostgresSQL tables I need to zip/tar or gz
up somehow, from within Python for archival/backup purposes.
Anyone know of an example of this, or some idea how to do or approach
this? Thanks, RVince

Is there a way I can casr this ResultProxy obect to a usable object
here (like tuples?) Thanks, RVince

I found the answer. I needs to be wrapped in a transaction, like this:
engine = engine_from_config(config, 'sqlalchemy.')
connection = engine.connect()
trans = connection.begin()
try:
connection.execute('truncate table cms_history;')
'middle_initial'
In this kind of circumstance of joined tables, in the python code
itself (the Pylons controller, actually) how would I refer to the
member table's middle_initial field where the members table is joined
in with a left outer join via SQLAlchemy? Thanks again

Are you sure? Because I can already access those fields from he mako
page from that query -- shouldn't I be able to access them in the
Puython controller of that page? -RVince
