mysql cpp連接器在連接時拋出UnknownException

Question

我正在使用mysql庫連接到我的數據庫（mysql）以在連接後檢索數據。檢查我的服務是否正常運行。

以下是代碼，不會連接任務的一部分。這

// Specify our connection target and credentials 
const string server = "tcp://127.0.0.1:3306"; 
const string username = "root"; 
const string password = "";// No password - thanks, WAMP Server! 

// Try to get a driver to use to connect to our DBMS 
try { 
    driver = get_driver_instance(); 
    if(driver == NULL) 
     throw SQLException("Null driver instance returned."); 
} 
catch (SQLException e) { 
    cout << "Could not get a database driver. Error message: " << e.what() << endl; 
    return -3; 
} 

// Try to connect to the DBMS server 
try { 
    dbConn = driver->connect(server, username, password); 
} 
catch (sql::SQLException e) { 
    cout << "Could not connect to database. Error message: " << e.getSQLStateCStr() << " Error Code: " << e.getErrorCode() << endl; 
    cout << "Could not connect to database. Error: " << e.what() << endl; 
    return -1; 
} 

它編譯良好，但給出了一個未知異常未知的調試信息。像這樣的東西。請幫忙。

這改變string到SQLString所有連接PARAMS像server，username和password後工作。

這就像一個魅力。
