Hi Pumkin,

You can't reference an alias directly (except in the ORDER BY clause),
but you can do it indirectly if you use a derived table:

SELECT SQL, Oracle
FROM (SELECT Cod1 AS SQL, Cod2 AS Oracle
FROM YourTable) AS Der
WHERE SQL = 'one'
AND Oracle = 'two'
ORDER BY SQL ASC, Oracle DESC

>dinamically

Please read the following article very carefully:
