as already said by a few people on this list the DBAPI is not a
cross-database-backend tool. it is there to provide a common API, not to
guarantee database independence.

the whole DBAPI is _based_ on ambiguous mappings. i agree with marc on
that: it does not make sense to force a unique set of type mapping
because it would be too a burden on the module developers.

what we need is, imho, a way to tell that a STRING from a database can
be safetly mapped to a STRING on another backend. and so on. mm.. this
seems "protocols"[1] stuff to me.

i don't understand what you mean here (not a native english speaker,
sorry, i know this is my fault.)


[1] like in PyProtocols, google for it.
