using MySql.Data.MySqlClient;

namespace Database
{
    class DatabaseTest
    {
        public string connectionString = "SERVER=127.0.0.1; DATABASE=db; UID=root; PASSWORD=pw;";

        /// <summary>
        /// Get the Name from Database
        /// </summary>
        /// <param name="id">primary key</param>
        /// <returns>the name</returns>
        public static string GetName(int id)
        {
            using (MySqlConnection connection = new MySqlConnection(connectionString))
            {
                connection.Open();
                MySqlCommand command = connection.CreateCommand();

                command.CommandText = "SELECT * FROM `mytable` WHERE id = @id LIMIT 1";

                command.Parameters.AddWithValue("@id", id);
                //command.Parameters.AddWithValue("@somemore", somemore);

                using (MySqlDataReader reader = command.ExecuteReader())
                {
                    reader.Read();
                    return reader.GetString("name");
