C ++ Mysql连接失败

Question

我有第二个问题C ++＆amp; Mysql的， 应用程序符合正确，但当我尝试这个时，我有这样的消息：

root@raspberrypi:/home/pi/elementari/base# ./appkconnectalpha
terminate called after throwing an instance of 'sql::MethodNotImplementedException' appkconnectalpha main.cpp -L/usr/lib -lmysqlcppconn
what():  MySQL_Connection::setReadOnly()
Aborted

代码是：

#include <iostream>
#include <stdlib.h>
#include <mysql_connection.h>
#include <mysql_driver.h>
#include <cppconn/exception.h>
#include <cppconn/resultset.h>
#include <cppconn/statement.h>

using namespace std;

int main(void){
  sql::Driver *driver;
  sql::Connection *con;
  sql::Statement *stmt;


  driver = get_driver_instance();
  con = driver->connect("tcp://127.0.0.1:3306","********","***********");
  con->setSchema("Elem_elems");
  stmt = con->createStatement();
  delete stmt;
  delete con;
  return 0;
}
