There are two problems I can see.
1. there is no end control for variable i 2. res is a vector (i guess), res.at(i) will out of boundary when i is exceed the size

Problem with "mysqlpp:Result"

I have this little problem, if i use this code of exemple: if (res) {

                                 mysqlpp::Row row;
                                 mysqlpp::Row::size_type i;
                                 for (i = 0; row = res.at(i); ++i) {
                                                 cout << '\t' << row.at(0) 
<< endl;
                                 }
                 }

My executable stop with "This application has requested the Runtime to terminate it in an unusual way.Please contact the application's support team for more information."

I solve with this trick...
if (res) {

   mysqlpp::Row row;
   mysqlpp::Row::size_type i;
   for (i = 0; i < res.size(); ++i){

       row = res.at(i);
  out << '\t' << row.at(0) << endl;
   }

My question is why the first code rise errors?
