Hello
I am trying to connect MySQL database from C++ code given below-
My development environment is -
Window 7
CODE::BLOCKS 10.05 with minGW mingw32-g++.exe
MySQL Connector C++ 1.0.5\lib\debug\mysqlcppconn.lib
Up to compilation and linking every thing is OK I followed the tutorial http://dev.mysql.com/doc/refman/5.1/en/connector-cpp-examples-complete-example-1.html
#include <stdlib.h>
#include <iostream>
#include <winsock2.h>
/*
Include directly the different
headers from cppconn/ and mysql_driver.h + mysql_util.h
(and mysql_connection.h). This will reduce your build time!
*/
#include "mysql_connection.h"
#include <cppconn/driver.h>
#include <cppconn/exception.h>
#include <cppconn/resultset.h>
#include <cppconn/statement.h>
using namespace std;
int main(void)
{
cout << endl;
cout << "Running 'SELECT 'Hello World!' AS _message'..." << endl;
try {
sql::Driver *driver;
sql::Connection *con;
sql::Statement *stmt;
sql::ResultSet *res;
cout << "Running 'SELECT 'Hello World!...1' AS _message'..." << endl;
/* Create a connection */
driver = get_driver_instance();
cout << "Running 'SELECT 'Hello World!...2' AS _message'..." << endl;
con = driver->connect("tcp://127.0.0.1:3306", "root", "");
cout << "Running 'SELECT 'Hello World!...3' AS _message'..." << endl;
/* Connect to the MySQL test database */
con->setSchema("bill");
cout << "Running 'SELECT 'Hello World!...1' AS _message'..." << endl;
stmt = con->createStatement();
res = stmt->executeQuery("SELECT 'Hello World!' AS _message");
while (res->next()) {
cout << "\t... MySQL replies: ";
/* Access column data by alias or column name */
cout << res->getString("_message") << endl;
cout << "\t... MySQL says it again: ";
/* Access column fata by numeric offset, 1 is the first column */
cout << res->getString(1) << endl;
}
delete res;
delete stmt;
delete con;
} catch (sql::SQLException &e) {
cout << "# ERR: SQLException in " << __FILE__;
cout << "(" << __FUNCTION__ << ") on line " << __LINE__ << endl;
cout << "# ERR: " << e.what();
cout << " (MySQL error code: " << e.getErrorCode();
cout << ", SQLState: " << e.getSQLState() << " )" << endl;
}
cout << endl;
return EXIT_SUCCESS;
}
When I run the code it shows
SELECT 'Hello World!
SELECT 'Hello World!....1
SELECT 'Hello World!....2
And then Debug window open with a message "bill.exe has stopped working", I copied libmysql.dll to my application debug folder.
My assumption is that this line is raising problemcon = driver->connect("tcp://127.0.0.1:3306", "root", "");
May be require some port or network related file.
Any idea or advice will be great help for me.
