PAGEID from item_id or caid

Question

I would like to get default pageid(ca_page) for displaying
content area from item_id (or folder_id or caid. I need it to
display any item between other elements of content area page.
Anybody knows where to find the connection between pageid and
content area elements?
Thanks,
Marko

I have url items stored in different content areas. My goal is
to make a function URL_ITEM_LINK which would return the url link
for displaying any item in the default content area page.
The function URL_ITEM_LINK has parameter Item_id and
concatenates other parameters from DB to url links like
'http://multiserver:8000/servlet/page?
pageid=161&dad=portal30&_schema=PORTAL30&_type=site&_fsiteid=13
4&_fid=8911&_fnavbarid=1&_fnavbarsiteid=134&_fedit=0&_fmode=2&_fd
isplaymode=9&_fcalledfrom=1&_fdisplayurl=http%3A%2F%
2Fmultiserver%2Foralab%2Ftest.htm'(same as when you click on the
content area item if you used url item).
All the values for these links I got from the DB except
of '_pageid=161'. Items are stored in content areas so instead
of using _pageid=161 for every item I would like to get the
page_id from DB (from item_id or caid).
So far I am able to get fsite_id, folder_id, fdisplay_url and
everything else from Item_id except of page_id. I can't find the
connection in DB from caid to its ca_page id.
Hope this makes my question more clear? Anybody knows any other
ways for diplaying url item in its content area ca_page?
