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
