Обсуждение: URGENT: Using function inside query

I need some help on the following problem.  I have an account info
table that has a hierarchy of accounts.  The grouping goes from end
user to organization to reseller.  I have a PL/SQL function written
that gives me the tree, so I just whittle it down by selecting the one
id for a reseller:

select account_id from roll_account(1186) where hierarchy_type_id = 2


The problem is I have data like this:

account id    name

1    Company A
2    Company B
3    Company C
4    Person 1 (in Company A)
5    Person 2 (in Company A)

If I pass it the number of let's say Person 2 -- the above query wold
give me the account id of 1.    How can I do a query using that
function so that it automatically inserts the account_id to show the
"rolled up" account id ?

I'm not sure I follow -- what account_id are you trying to insert
and where are you trying to insert it?  Do you want something like
this?

SELECT account_id
FROM roll_account( (SELECT account_id FROM account_info WHERE name = 'Person 2')
)
WHERE hierarchy_type_id = 2;

If that's not what you're after then please provide an example of
the kind of query you'd like to make and what results you expect.
