PATH and UNDER_path functions in ORACLE 11gR2 for Windows.

Question

I am now getting the error -01405 when I use the function and predicate PATH UNDER_PATH path_string use the parameter function. If instead you use a literal value everything works fine. I found that if I delete from the list select the same path expression works well. example:
SELECT PATH(1), e.xmldata.dispname FROM xdb.xdb$resource e
WHERE UNDER_PATH(VALUE(e),funcionRetornaUnPath,1) = 1
!!!!Error ora - 01405
SELECT PATH(1), e.xmldata.dispname FROM xdb.xdb$resource e
WHERE UNDER_PATH(VALUE(e),'/pathxxxx',1) = 1
!!!! OK.
SELECT e.xmldata.dispname FROM xdb.xdb$resource e
WHERE UNDER_PATH(VALUE(e),funcionRetornaUnPath,1) = 1
!!! Ok.
Thank´s

Hi,
First of all, you shouldn't be using XDB$RESOURCE directly but RESOURCE_VIEW or PATH_VIEW instead.
It doesn't solve the problem entirely but there's no error if we declare the function DETERMINISTIC.
However the PATH function returns NULL :
SQL> create or replace function fnc_test return varchar2
  2  deterministic
  3  is
  4  begin
  5   return '/public';
  6  end;
  7  /
Function created
SQL> select path(1), v.any_path
  2  from resource_view v
  3  where under_path(v.res, fnc_test(), 1) = 1
  4  ;
PATH(1)               ANY_PATH
                      /public/dump
Could you post again in the {forum:id=34} forum?
Thanks.
