Follow the following steps to select a single colume, and display them.

    //create a connection
    SqlConnection sqlConnection = new SqlConnection("Your Connection String");
    SqlCommand cmd = new SqlCommand();
    cmd.Connection = sqlConnection;

    //open the connection
    sqlConnection.Open();

    //Your command query string
    cmd.CommandType = CommandType.Text;
    cmd.CommandText = "SELECT TOP 1 col_name FROM Customers";


    //Execute the reader
    SqlDataReader result  = cmd.ExecuteReader();
    result.Read();

    //close the connection
    sqlConnection.Close();

    return result["coiumn_name"].ToString();
