Sybase ASE connect by level equivalent

I want to generate numbers from 0 to 9000000. In Oracle, I can use the below code. How do I do this in Sybase ASE?

This is in Oracle:

SELECT level  Num
FROM DUAL
CONNECT BY LEVEL  <= 9000000
ORDER BY Num;

How to do this in Sybase ASE?

I cannot create a table and add an identity, because I need the numbers from 1 to 9000000, so a table will be complex. Is there a query to do this?
