the reason i, at least, like sqlalchemy so much is for exactly the reasons
you outlined. unlike other orm solutions it doesn't force you to use orm.
you can also use sql directly - either as simple strings or by
constructing it via python methods (which can be a very powerful way of
programatically constructing sql commands that would be a nightmare to
write by hand). that gives you the flexibility to deal with each problem
in the way that feels most natural, without having to switch between tools
(in fact, i have mixed orm and "direct" sql in a single project with no
problems using sqlalchemy - reading from one database using sql and
writing to another using objects).
