execution view

Hi,

I've a very simple view:

CREATE OR REPLACE FORCE VIEW xxxxx

(  KOL1,  KOL2 )

BEQUEATH DEFINER

AS

  SELECT samecolumn, samecolumn FROM tablexx;

So the view references to the samecolumn twice. And my question is:

will Oracle fetch the column once on twice?

I tried to trace the execution with ALTER SESSION SET EVENTS '10046 trace name context forever, level 12'; and ALTER SESSION SET EVENTS '10053 trace name context forever, level 12';

and some other events but I don't see it. I assume Oracle will fetch the value once but want to know exactly how Oracle executes this.

regards,

Ivan
