i am having a table with 3 col. viz id,profile_id,plugin_id.there can be more than 1 plugins associated with a single profile now how can i fetch from the database all the plugins associated with a profile_id which comes from the session variable defined in the login page when I try to apply the query for the same it returns the data with the plugin_id of the last record the query is as follows

SqlCommand cmd1 = new SqlCommand("select plugin_id from profiles_plugins where profile_id=" + Convert.ToInt32(Session["cod"]), con);

    SqlDataReader dr1 = cmd1.ExecuteReader();
    if (dr1.HasRows)
    {
        while (dr1.Read())
        {
            Session["edp1"] = Convert.ToInt32(dr1[0]);
        }
    }
    dr1.Close();
    cmd1.Dispose();
