Hi Syed,

this is a very strange usage of ROWNUM in Oracle, i didn't know this returns a correct result without aliasing it in the derived table:

     MIN (ROWNUM) AS min_rownum

Is there a huge difference between both queries or just a few rows? Could you test it with just a small subset of data?
