c++ - 从Eclipse(CDT)连接到MySQL

我尝试使用Internet上的所有建议通过Eclipse中的C++连接到MySQL数据库，但是它们中没有一个完全有用。我将Eclipse与MinGW结合使用以连接到MySQL。
我添加了:

C:\Program Files\boost
C:\Program Files\MySQL\MySQL Connector C++ 1.1.3\include
C:\Program Files\MySQL\MySQL Server 5.6\include

到包含目录和

C:\Program Files\MySQL\MySQL Server 5.6\lib
C:\Program Files\MySQL\Connector C++ 1.1.2\lib\opt

到图书馆目录(-L)。我也添加了

libmysql.lib
mysqlcppconn-static.lib

到其他依赖项(-l)。

代码是:

#include <stdlib.h>
#include <iostream>

#include "mysql_driver.h"
#include "mysql_connection.h"

#include <cppconn/driver.h>
#include <cppconn/exception.h>
#include <cppconn/resultset.h>
#include <cppconn/statement.h>

using namespace std;
using namespace sql::mysql;

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;

  /* Create a connection */
  driver = get_driver_instance();
  con = driver->connect("tcp://127.0.0.1:3306", "root", "root");
  /* Connect to the MySQL test database */
  con->setSchema("test");

  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;
}

但是它们似乎都不起作用，并且会弹出很多错误。现在我得到一个错误"call of overloaded 'get_driver_instance()' is ambiguous"你们是否有经验在C++环境中通过Eclipse连接到MySQL。我不是Linux用户，Linux上的教程也不起作用。

最佳答案

只是代替这个

driver = get_driver_instance();

这样

 driver = sql::get_driver_instance();

这只是一个 namespace 问题；
