SqlCommand("GetOrdersInfo",myConn)里面的"GetOrdersInfo"是什么意思

请问以下红色字体那句中的 "GetOrdersInfo"是什么意思啊,,是字符串没错吧,,但也应该要sql的字符串才对啊,
那位高手能帮帮忙解译一下

SqlConnection myConn = new SqlSqlConnection(ConfigurationManager.AppSettings["ConnectionString"].ToString());
        myConn.Open();
       SqlCommand cmd = new SqlCommand("GetOrdersInfo",myConn);
         = CommandType.StoredProcedure;
        SqlParameter userIP = new SqlParameter("@UserIP",SqlDbType.VarChar,50);
        userIP.Value = Convert.ToString(Request.UserHostAddress);
        cmd.Parameters.Add(userIP );
        cmd.ExecuteNonQuery();
        SqlDataAdapter da = new SqlDataAdapter(cmd);
        DataSet ds = new DataSet();
        da.Fill(ds,"Orders");
        GridView1.DataSource = ds.Tables["Orders"].DefaultView;
        GridView1.DataBind();
        cmd.Dispose();
        myConn.Close();
