Ilearning Course Structure

Question

Hi, I was wondering if I could get some help on extracting course/session information from the ilearning schema.
We have in ilearning a number of courses which have nested levels of categories/folders followed by offerings i.e the scorm item. The data is viewable as tree heirarchical tree structure in ilearning admin screens
What I am trying to do is collate the nested structure into a single record for each scorm item i.e. offering
For example Driving Test/Highway Code/Signs would be a common structure I would be looking to obtain althougth the levels could be more than the 3 I have specified.
I have identified the follwing ilearning tables as possible areas to query:
OFFERING
CATEGORY
OFFERING_CATEGORY
CONTENT_OBJECT
CATEGORY_TREE_XREF
OFFERING_CONTENT_OBJECT
FOLDER
However, I have been unable to successfully retrieve the information based on the example above.
Any help would be greatfully appreciated as I am in need of a solution imminently.
Thanks

Hi there,
Got this worked out. Ideally it's best if categories are assigned at the course object level (select the object in the tree on the left hand side then More->Categories and assign from there, as you only have to do it once for each course rather than assigning categories for each offering of the same course).
Category Structure by Course (content object)
Parameter: Content Object ID
select
rco.id rcoid, rco.title course_title, cat_structure.cat_path
from
content_object rco,
content_object_category coc,
select cat.child_id,
cat.name,
cat.parent_id,
ltrim(sys_connect_by_path (replace(cat.name,' / ',' - '),' / '),' / ') cat_path
from
(select id child_id, name, null parent_id
from category
where id IN
     /* get all top level categories */
     (select cat1.id
     from category cat1
     where
     not exists
          (select 1
          from subcategory subcat
          where cat1.id = subcat.child_id
union all
select subcat.child_id, cat.name, subcat.parent_id
from subcategory subcat,
category cat
where cat.id = subcat.child_id
) cat
start with cat.parent_id is null
connect by prior cat.child_id = cat.parent_id
) cat_structure
where
rco.id = coc.content_object_id and
coc.category_id = cat_structure.child_id and
rco.id = &rcoid
Category Structure by Offering
Parameter: Offering ID
select
rco.id rcoid, rco.title course_title, o.id offeringid, o.name offering_name, cat_structure.cat_path
from
content_object rco,
offering o,
offering_category oc,
select cat.child_id,
cat.name,
cat.parent_id,
ltrim(sys_connect_by_path (replace(cat.name,' / ',' - '),' / '),' / ') cat_path
from
(select id child_id, name, null parent_id
from category
where id IN
     /* get all top level categories */
     (select cat1.id
     from category cat1
     where
     not exists
          (select 1
          from subcategory subcat
          where cat1.id = subcat.child_id
union all
select subcat.child_id, cat.name, subcat.parent_id
from subcategory subcat,
category cat
where cat.id = subcat.child_id
) cat
start with cat.parent_id is null
connect by prior cat.child_id = cat.parent_id
) cat_structure
where
rco.id = o.content_object_id and
oc.category_id = cat_structure.child_id and
oc.offering_id = o.id and
o.id = &offeringid
Enjoy!
