Insert data from a table and with parameters

I have 2 tables, one feeds data for another but I must add external value too

Is this query does the job ?

MySqlCommand cmd1 = new MySqlCommand("INSERT INTO tableA (dt1, dt2) SELECT (dt1, dt2) FROM tableB, @dt3, @dt4",conn1);

cmd1.Parameters.Add("@dt3", MySqlDbType.Int16).Value = 2;
cmd1.Parameters.Add("@dt4", MySqlDbType.Int16).Value = 0;

And would Update TableA with

LastId = Convert.ToInt32(cmd1.LastInsertedId);

Is it possible in one query ? And help will be very precisous.
