I am using SQLAlchemy as well in one of my apps, and I didn't have
this kind of problems... I suspect you are using a different "backend"
in SQLAlchemy (i.e., I use it to access SQLite, while I think you are
using Firebird or whatever is its name :-D ). Could Firebird be the
problem (or its links to SQLAlchemy)?
