Sure you didn't mean "hundreds OF thousands"? :)

We're using SQLAlchemy sharding to partition accounts across a couple
of databases. We want to add more partitions, but first we need to
eliminate some unnecessary cross-partition queries.

Let's say I have a database with hundreds or even thousands of tables.
The table structure for this set of tables is *exactly* the same.
Furthermore, let's say the name of each table is predictable.
For example, something like:
tablename_2010_03_05

Hrm, pep-249 seems to only specify "sequence" and "sequence of
sequences" for the fetch*() functions, specifying list of tuples only
as one possible example. Perhaps the C implementation of RowProxy is
being too strict here? I'm

Hi all,
I have some troubles creating my db schema with Oracle. The problem is

The underlying column returns a Decimal object when queried regularly,
