Witam,
Dopiero zaczynam swoją przygodę z C++.
Dodam że program piszę w C++/CLI.
Chcę uruchomić przykład znaleziony w sieci.
#include "stdafx.h"
//using namespace std;
sql::Driver *driver;
sql::Connection *con;
sql::Statement *stmt;
sql::ResultSet *res;
sql::PreparedStatement *pstmt;
void polacz(){
try {
/* Create a connection */
driver = get_driver_instance();
con = driver->connect("tcp://192.168.8.2:3306", "root", "root");
/* Connect to the MySQL test database */
con->setSchema("test");
stmt = con->createStatement();
stmt->execute("insert into example values(4,'four'),(5, 'five')");
delete stmt;
pstmt = con->prepareStatement("select * from example");
res = pstmt->executeQuery();
while (res->next())
std::cout<<res->getInt("id")<<" "<<res->getString("data")<<std::endl;
delete res;
delete pstmt;
pstmt = con->prepareStatement("delete from example where id=?");
pstmt->setInt(1,4);
pstmt->executeUpdate();
pstmt->setInt(1,5);
pstmt->executeUpdate();
delete pstmt;
delete con;
}catch(sql::SQLException &e){
std::cout<<e.what();
std::cout << "# ERR: SQLException in " << __FILE__;
std::cout << "# ERR: " << e.what();
std::cout << " (MySQL error code: " << e.getErrorCode();
}
}
