AFAIK when you request a string, whatever value is there gets
converted to string. Or you can just add code to extract blobs,
that would be less effort than writing everything from scratch.
You can also look here
https://github.com/cruisercoder/dstddb/blob/master/src/std/database/odbc/database.d for an example of accessing ODBC from D (only strings are supported so far).
Latest version of what? ODBC bindings are in phobos:
http://dlang.org/phobos/etc_c_odbc_sql.html
Also there's ODBC driver
http://www.firebirdsql.org/en/devel-odbc-driver/ - you can use
it, phobos has ODBC bindings.
Mingw or windows platform SDK.
When a string is not an in parameter, it can't be declared `in
char[]`.
