Subj:   Re: Order and Level
From:   Victor Sokovin

  On the fly i need to arrange the records and introduce column ORD and LEVEL.  

I suggest to read the parallel thread with the "previous row" puzzle and then perhaps open the manuals describing OLAP functions such as RANK() or ROW_NUMBER(). This is all you really need to solve your problem yourself. I don't think that this particular puzzle is interesting enough for a separate discussion when a similar one has just been discussed in all due depth.

Could be just my opinion, though.
