Veritabanı sorgusu C# çalışmıyor

Question

Ağdaki C# için birçok ODBC öğreticisini okudum ve bu kod bana hata vermeyen tek koddur. Ama sorun şu ki, hiçbir şey yapmıyor -... Nasıl düzeltilir?

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Windows.Forms; 
using System.Data.Odbc; 
using System.Data.Sql; 
namespace WindowsFormsApplication1 
{ 
    static class Program 
    { 
     /// <summary> 
     /// The main entry point for the application. 
     /// </summary> 
     [STAThread] 
     static void Main() 
     { 
     string connectionString = "Server=localhost;User  ID=root;Password=****;Database=testing;Port=3306;Pooling=false"; 
     MySql.Data.MySqlClient.MySqlConnection connection = new MySql.Data.MySqlClient.MySqlConnection(connectionString); 

     connection.Open(); 

     string insertQuery = "ALTER TABLE `user` ADD lol INT (15)"; 
     MySql.Data.MySqlClient.MySqlCommand myCommand = new MySql.Data.MySqlClient.MySqlCommand(insertQuery); 
     connection.Close(); 
     Application.EnableVisualStyles(); 
     Application.SetCompatibleTextRenderingDefault(false); 
     Application.Run(new Form1()); 
    } 
} 
} 

Answer 1

Sen komutu çalıştırmak gerekir:

myCommand.ExecuteNonQuery(); 

Answer 2

düzenli beni izin vermeyi; önemli noktalar: Ben öneririm

Application.EnableVisualStyles(); 
Application.SetCompatibleTextRenderingDefault(false); 
string connectionString = "Server=localhost;User ID=root;Password=****;Database=testing;Port=3306;Pooling=false"; 
string insertQuery = "ALTER TABLE `user` ADD lol INT (15)"; 
using(MySql.Data.MySqlClient.MySqlConnection connection = 
    new MySql.Data.MySqlClient.MySqlConnection(connectionString)) 
using(MySql.Data.MySqlClient.MySqlCommand myCommand = 
    new MySql.Data.MySqlClient.MySqlCommand(insertQuery)) 
{ 
    myCommand.Connection = connection; 
    connection.Open(); 
    myCommand.ExecuteNonQuery(); 
    connection.Close(); 
} 
using(Form1 form1 = new Form1()) { 
    Application.Run(form1); 
}
