Subselects, the Oracle way

Hi,

Is there any way to mimic the oracle way of subselect, especially
constructs like

select * from (select col1 as x, col2, col6 from t1 union select col2
as x, col6, col2 from t2) y order by y.x

I am aware of the fact, that it is possible to accomplish through the
use of tempoary tables, but would rather not use them.

Thanks in advance

Svenne
