И у меня есть поиск и тот же вопрос в StackOverflow, но это не имеет должного ответа. и мой код:
#include <iostream>
#include <string>
#include <mysql_connection.h>
#include <mysql_driver.h>
#include <cppconn/driver.h>
#include <cppconn/exception.h>
#include <cppconn/resultset.h>
#include <cppconn/statement.h>
#include <cppconn/prepared_statement.h>
using namespace std;
void RunConnectMySQL()
{
sql::mysql::MySQL_Driver *driver = NULL;
sql::Connection *con = NULL;
Statement *state = NULL;
ResultSet *result = NULL;
try
{
driver = sql::mysql::get_mysql_driver_instance();
con = driver->connect("tcp://127.0.0.1:3306","root","");
state = con->createStatement();
state->execute("use monitor");
result = state->executeQuery("select * from address");
}
catch(sql::SQLException & ex)
{
cout<<ex.what()<<endl;
return;
}
while(result->next())
{
cout<<"source: "<<result->getString("source").c_str()<<endl;
}
state->close();
}
int main()
{
RunConnectMySQL();
system("pause");
return 0;
}
Спасибо.
