how to connect multiple table with dataset

Hi,

In my application ,iam using stored procedure.and that stored procedure return values from 2 tables

means 2 select queries.

my problem is ,i want to connect this with dataset.

i tried like this

using (SqlCommand cmd = new SqlCommand("Sp_selconductorTest", con))
                {
                    cmd.CommandType = CommandType.StoredProcedure;
                    cmd.Parameters.AddWithValue("@tourdate", tDate);
                    cmd.Parameters.AddWithValue("@busid", busid);
                    con.Open();
                    SqlDataAdapter da = new SqlDataAdapter(cmd);

                    DataSet ds1 = new DataSet();
                    DataSet ds2 = new DataSet();
                    da.Fill(ds1.Tables[0]);

                    da.Fill(ds2.Tables[1]);

}

this showing error.

if i try

da.Fill(ds1);

it displays first table values.

How to take value of second table?
