Roland,
Sorry I didn't see your reply. I even sent a second message without seeing
this.
Answering your question on database APIs for bin transfer, I don't know of
any. I always use top layers, like SOCI. I use it heavily.
If you wish to see details about binary transfer I suppose the SOCI authors
could give you pointers on those, and maybe the archives for this ML when
that discussion was going on. Not sure, though.
