前言：
I don't really understand why they made a C++ wrapper for the C API (MySQL++ = http://www.tangentsoft.net/mysql++/ ) because shouldn't the C API work in C++?
The mysql C api will work in C++ - I suppose someone just wanted to do a c++ wrapper.

1. SOCI http://soci.sourceforge.net/index.html
SOCI is a database access library for C++ that makes the illusion of embedding SQL queries in the regular C++ code, staying entirely within the Standard C++.
The idea is to provide C++ programmers a way to access SQL databases in the most natural and intuitive way. If you find existing libraries too difficult for your needs or just distracting, SOCI can be a good alternative.
