You already implement int and short. What is the difference in unsigned int
and signed int? It is
semantical and there is no difference in data representation. SQL doesn't have
unsigned
representation, but all signed maps to unsigned directly without any data loss.
So, why we cannot
map C++ unsigned int to SQL INTEGER and C++ unsigned short to SQL SHORT?
