ado.net begin informix transaction

Hi,

Is there any one used the following way to open a INFORMIX transaction
in ADO.NET?

OleDbConnection conn = new OleDbConnection(connString);
OleDbCommand cmd = new OleDbCommand("Begin Work", conn);
cmd.ExecuteNonQuery();
//....Do the other works .....//
cmd = new OleDbCommand("Commit Work", conn);

Or

OleDbConnection conn = new OleDbConnection(connString);
OleDbTransaction trans = conn.BeginTransaction();
OleDbCommand cmd = new OleDbCommand("Update XXX", conn); //Please
notice that the transaction object is not passed in..
cmd.ExecuteNonQuery();
trans.Commit();

This is not followed the way how ADO.NET handles the transaction. But
it works. Does anyone know if the above code will have any problem?

Thanks.
