How to manipulate nested varrays?

Question

This is my Schema. "Botany" table has this attribute called content_ip which is of type IP_TY. IP_ty is described below.
DESC botany
Name Null Type
LANG VARCHAR2(15)
AUTHOR VARCHAR2(15)
CHAPTER_NO NUMBER
TITLE VARCHAR2(15)
CONTENT VARCHAR2(15)
CONTENT_IP                              IP_TY()
DATE_PUBLISHED DATE
LAST_UPDATE DATE
DESC ip_ty
user type definition
TYPE ip_ty
AS OBJECT
aip aip_ty, cip cip_ty, pip pip_ty
DESC aip_ty
user type definition
TYPE aip_ty AS VARRAY(3) OF VARCHAR(15)
DESC cip_ty
user type definition
TYPE cip_ty AS VARRAY(3) OF VARCHAR(15)
DESC pip_ty
user type definition
TYPE pip_ty AS VARRAY(3) OF VARCHAR(15)
SELECT bot.content_ip.aip, bot.content_ip.cip, bot.content_ip.pip
FROM botany bot
here is the output for the above queries.
CONTENT_IP.AIP CONTENT_IP.CIP CONTENT_IP.PIP JOEY.AIP_TY('administration','write') JOEY.CIP_TY('marketing') JOEY.PIP_TY('guest')
the problem is how do i get the output without the leading JOEY.AIP_TY or JOEY.CIP_TY.
is the above schema too much screwed :( ?
will casting ip_ty to a table do the trick? i have tried. but vain. maybe it failed due to my ignorance. shed some light if "casting" will remove those leading text.

Answer 1

will casting ip_ty to a table do the trick?not sure what you are after, but maybe you mean sth like
SQL> create or replace type ip_ty as object
   (aip sys.odcivarchar2list,
    cip sys.odcivarchar2list,
    pip sys.odcivarchar2list
Type created.
SQL> with botany
        as (select ip_ty (sys.odcivarchar2list ('some aip'),
                          sys.odcivarchar2list ('some cip'),
                          sys.odcivarchar2list ('some pip1', 'some pip2')
                         ) content_ip
              from dual
select aip.column_value aip, cip.column_value cip, pip.column_value pip
  from botany t,
       table (t.content_ip.aip) aip,
       table (t.content_ip.cip) cip,
       table (t.content_ip.pip) pip
AIP                  CIP                  PIP                
some aip             some cip             some pip1          
some aip             some cip             some pip2          
2 rows selected.
