Ah, I was trying to understand how the size would work until I realized it is for fixed-sized elements! > Attached is a patch for the added void * type.

Would it be acceptable (for your use-case) to implement the sql_value_traits<> specializations to convert between a std::vector<> and void * so that the back-end interface (SqlStatement *) is not affected ? Or is the extra copy something that would hurt performance ?
