I can't disagree that the documentation is minimal.  Some real-world
code samples would help tremendously.
I think the answer to your question can be found in the PEP -- look at
the "paramstyle" attribute.
Apparently the portable way to do parameters is to query the
paramstyle attribute and put your query together using the appropriate
style.  The alternative would be to have all the drivers support a
'standard' form of parameters, and convert to the database-specific
one on the fly.  Maybe in DBAPI 3.0.
