Question

I’m adding a record into remote mysql database and after that I want to check if it’s added – So i want to try to select this particular record.

My code:

    public void Select(string filename)
    {
        string query = "SELECT * FROM banners WHERE file = '"+filename+"'";

        //open connection
        if (this.OpenConnection() == true)
        {
            //create command and assign the query and connection from the constructor
            MySqlCommand cmd = new MySqlCommand(query, connection);

            //Execute command
            cmd.ExecuteNonQuery();

            //close connection
            this.CloseConnection();
        }
    }

How to check the response from the server? Or selected records?
It’s c# windows forms app.

Try this:

public void Select(string filename)
{
        string query = "SELECT * FROM banners WHERE file = '"+filename+"'";

        //open connection
        if (this.OpenConnection() == true)
        {
                //create command and assign the query and connection from the constructor
                MySqlCommand cmd = new MySqlCommand(query, connection);

                //Get the DataReader from the comment using ExecuteReader
                            MySqlDataReader reader = cmd.ExecuteReader(); 
                while (myReader.Read())  
                { 
                    //Use GetString etc depending on the column datatypes.
                    Console.WriteLine(myReader.GetInt32(0)); 
                } 

                //close connection
                this.CloseConnection();
        }
}
