Re: inline views & unions & other schemas; ora 9.2.0.6 bug?

P.S. due to the sheer no. of records and complexity of already existent code/views, if I can help it, I'd rather look for a purely sql/set based solution, rather than one that involves PL/SQL, unless one is comparably fast :-)    

  thx again,

    hello all, I'm getting an ORA-03001 --"unimplemented feature" when I'm trying to select off a view based on other views (in turn based on other views... multiple levels, etc) containing UNIONS and INLINE VIEWS, in some pretty big ORA Apps modules.    

  I am **only** getting this error when querying from a different schema, and even then, it happens intermittently, on some instances, on some particular selects in a long UNION set.    

  I do not get the error when trying to select **from within** the owner's schema.   I've tried to reduce the problem to the simplest tables/queries but still cannot put my finger on the issue other than the fact that..the problem seems to go away if I do not use UNION to pull in more sets data.... however this is needed... I traced this to a Metalink article:    

  Subject: Ora-3001: "Unimplemented Feature" On Query Using "WITH" and FGAC   Doc ID: Note:361345.1 Type: PROBLEM   Last Revision Date: 15-MAR-2006 Status: MODERATED

  Has anyone seen anything like this before, ...how can this typically be circumvented?   (I have query_rewrite_enabled=true, etc)    

  my initial thought would be to create/populate some adhoc global temporary tables, do this preloading of a pretty huge ora apps summary beforehand.... or...fix this somehow (the part I'm interested).... or basically to turn (simplistically speaking) a query such as   line1, 1,2,3,4,5,6 from dual (a horizontal layout) into a vertical one   line1
  1
  2
  3
  4
  5    

  in effect eliminating the current UNIONS which are causing me this current headache?    

  thx much,
  Cosmin
