Hi,
I'm not a SQLAchemy expert ( just an average user... ). I have an
application that's causing me some problems... It's a monitoring
application that connects to a MS Sql Server, so it's always on.
Sometimes happens that casualy I have a DBAPIError with pyodbc. The
error is something like

I guess I'm kind of confused as to how it's supposed to create a table
that it doesn't even really know about yet. It hasn't successfully
reflected the table yet, so shouldn't know anything about its
structure. It seems like it'd just create an empty table at this
point.

Hey Greg, please set the output format to text (if you're in mssql 2005,
there's a button over the query window with a tooltip that should say
Results to text) and re-run the query. The text output will be a lot
easier to read.
Thanks

Hello all,
I have a question about SQLAlchemy when dealing with joining on one-to-
many relationships.
When I try to load data with eager=True for relation with objects,
which subclasses from some base class, SQLAlchemy generates query with
subselect.
Subselects are quite painful for me, as I'm
I have a web application which is accessed from different sub-domains.
Each sub-domain corresponds to one row/object in installation table.
I am fetching this one row/object on every request which is
unnecessary.
My question is: how can I fetch this object only once and somehow
stuff it inside a
the session.merge() method is provided with a flag dont_load=True to
assist in common caching scenarios. it copies the state of a cached
object into a given session so that you get the benefits of globally
cached state combined with no data shared between sessions.

Perhaps someone could offer some guidance here. I am trying to make a

concatenation of two fields from different tables, both joined to the
mapped table.

Thanks Michael!
Properly was a poor choice of words on my part. Yes, of course, == is
overloaded to make where (etc) clauses pretty, I just didn't put two and two
together.

Yeah, that sounds like a good approach. I'll have a look later today.
Attached is an untested patch against trunk that uses only kwargs to build
out the tabledef. I

This project moves so fast.
I guess it's time to reread the documentation. Again.
Knowing how great this project is, it was silly of me not to
expect SQLAlchemy ho have such functionality built in into
the public interface: I was kinda expecting to play with the
object state or who knows what.
Thank you, Michael, it was very helpful!
