OracleConnection conn = new OracleConnection("Data Source=Oracle8i;Integrated Security=yes");
Conn.Open;
OracleCommand cmd = conn.CreateCommand();
cmd.CommandText = "sp_pkg.getdata";
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(new OracleParameter("a1",OracleType.Cursor)).Direction = ParameterDirection.Output;
cmd.Parameters.Add(new OracleParameter("a2",OracleType.Cursor)).Direction = ParameterDirection.Output;
DataSet ds = new DataSet();
OracleDataAdapter adapter = new OracleDataAdapter(cmd);
adapter.Fill(ds);
