using System;
using MySql.Data.MySqlClient;

class Program
{
    static void Main(string[] args)
    {
        string connectionString = "server=localhost;user=root;password=password;database=test";
        string insertCommand = "INSERT INTO my_table (guid) VALUES (@guid)";

        using (MySqlConnection connection = new MySqlConnection(connectionString))
        {
            connection.Open();

            Guid guid = Guid.NewGuid();
            string guidString = guid.ToString();

            using (MySqlCommand command = new MySqlCommand(insertCommand, connection))
            {
                command.Parameters.AddWithValue("@guid", guidString);
                command.ExecuteNonQuery();
            }
