Back at Boost'Con 09 I proposed a function based and not text based SQL
interface using proto that looked like :
rows = select(age,name).from(employee)
.where( age > 45 && name
~= "Dil%" );
// Some random access
if( !r.empty() )
cout << r[name] << " is "
<< r[age] << " years old." << endl;
I have the whole ppt of my proposal somewhere if soemone's interested.
I have alas not much free time for this but I had some prototype code
