重新包含多个表的数据集asp.net c＃

Question

我正在执行3个选择查询，现在我想将3个不同查询的结果存储在不同的数据集表中，这样我就可以在不同的网格视图中显示不同的表，但是我得到索引超出范围异常，下面是我的代码 -

public DataSet viewdeal1（）

    {
        //string connectionString = "Data Source=INGNRILPSQL02;Initial Catalog=AHD08_A40;Persist Security Info=True;User ID=a36;Password=a36";
        string connectionString = @"Data Source=DELL-PC\SQLEXPRESS;Initial Catalog=Nikita;Integrated Security=True";

        string queryString3 = "Select PS3_Dealer.DealerID,DealerName,ContactNo,NoOfVehicles,CommittedDate from PS3_Dealer where CommittedDate<GETDATE()";



        SqlConnection connection = new SqlConnection(connectionString);
        connection.Open();

        SqlCommand sc = new SqlCommand(queryString3, connection);
        SqlDataAdapter da = new SqlDataAdapter(sc);
        DataSet ds = new DataSet();
        // sc.ExecuteNonQuery();
        da.Fill(ds.Tables[0]);

        string queryString1 = "Select PS3_Dealer.DealerID,DealerName,ContactNo,NoOfVehicles,CommittedDate from PS3_Dealer inner join (select DealerID from PS3_Vehicle inner join PS3_VehicleBooking on PS3_Vehicle.VehicleID!=PS3_VehicleBooking.VehicleID) as H on PS3_Dealer.DealerID=H.DealerID";
        SqlCommand sc1 = new SqlCommand(queryString1, connection);
        SqlDataAdapter da1 = new SqlDataAdapter(sc1);

        // sc.ExecuteNonQuery();
        da1.Fill(ds.Tables[1]);


        string queryString2 = "Select PS3_Dealer.DealerID,DealerName,ContactNo,NoOfVehicles,CommittedDate from PS3_Dealer inner join (Select DealerID from PS3_Vehicle inner join PS3_VehicleBooking on PS3_Vehicle.VehicleID=PS3_VehicleBooking.VehicleID where EndDate< GETDATE()) as Q on PS3_Dealer.DealerID=Q.DealerID";

        SqlCommand sc2 = new SqlCommand(queryString2, connection);
        SqlDataAdapter da2 = new SqlDataAdapter(sc2);

        // sc.ExecuteNonQuery();
        da2.Fill(ds.Tables[2]);










        connection.Close();



        return ds;
    }
