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$dual opposed to dual. from my reading
http://www.optimaldba.com/internals/oraint_dual.html Which refers to using the memort structure of X$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

thanks
bob
