> You'd need to do something like this under the SYS account:

		SQL> create view v_$dual
		2    as
		3    select dummy
		4    from x$dual
		5    where inst_id = userenv('INSTANCE');
		 
		View created.
		 
		SQL> grant select on v_$dual to public;
		 
		Permission granted.
		 
		SQL> create public synonym v$dual for v_$dual;
		 
		Synonym created.

	This would leave you with a publicly available view called

V$DUAL... Hope this helps...

Hello All

	Im looking to experiment with using x$dual opposed to dual.
	from my reading
	http://www.optimaldba.com/internals/oraint_dual.html
<http://www.optimaldba.com/internals/oraint_dual.html> 
	Which refers to using the memort structure of X$DUAL....
	
	if I 
	SQL>desc x$dual
	ORA-04043: object x$dual does not exist
	
	So how do I hook up x$dual??
	
	Ive searched orafaq, google, and comp.os.oracle.databases with

no avail

I recall this was a topic here a while back but nothing on how to create

x$dual if it dosnt exist??

	its not in this select
	select table_name from dba_tables where owner = 'SYS';
	
	Is this suposed to be an actual created table or a "memory
object" and
	how can I create/use in it place of dual
