Anyway, SQLAlchemy raises the error you see if you call fetchone()/all() on a

Why query(X).with_lockmode('update').all() is doing this appears to be some bug 
in your DBAPI, because all() emits a SELECT unconditionally.

It's MySQL-python = 1.2.3, has anyone seen this behaviour with that DBAPI?

cheers,
