Does anyone know if there are any DBD::drivers that do not use some

if desired/wanted.
As I understand it, DBI is agnostic to the database query language in
At least that is what the docs say :)
Ignoring what existing DBD:: support, do you see anything in the fundamental
DBI-defined API that is SQL specific and has no analogy for other DBMSs?
In my own effort to rewrite DBI itself (Muldis::Rosetta::Interface[|::*]) which
wasn't constrained to just SQL-think, I thought through various matters and
still ended up with fundamentally the same API that DBI has (Machine=driver,
Process=connection,...) and in particular found that it could easily be agnostic
to the DBMS query language and essentially just pass it through. The largest
design difference I have is that while DBI's interface wraps its driver
counterparts, Muldis' interface is just a set of roles which its drivers
("engines") compose and users invoke the driver/engine directly; hopefully DBIv2
will do likewise rather than continuing the wrapper approach.
Furthermore, to answer your other question ...
I'm not aware of any existing DBD:: that doesn't take some variant of SQL.
If that is the case, let the hate mail begin...
What hate mail, for what reason?
