Hi, I have a relation I'm mapping through an intermediate table and it
seems to work fine, it looks something like:
Content - ContentCollection - Content
'collection_children':relation(Content,
secondary = content_collection,
Hi
I've made a quick reference guide (cheat sheet) for SQLAlchemy for
myself and I thought I'd release it for every one:

Hello,
My application needs to run against Oracle and SQLite. I'd like to
have a query that uses a regexp in a select statement. For Oracle this
is fine, as it supports regular expressions natively. For raw SQLite I
can do:
connection.create_function(regexp, 2, regexp)
