No, you can't instantiate abstract class(w/ new). but you can use abstract class pointers.

btw, you don't need to create c/c++ objects - that's all done inside driver. but you have to delete all objects(except all kinds of metadata objects), supplied by driver, in your application, or it will leak memory.

so, using std::auto_ptr or boost::scoped_ptr(or maybe some other smart pointer) makes sense for connection, statement, resultset objects.
