How can I pass Recordsets as input parameter to a Function ?

Question

Hi Gurus,
I want to create a function that receive recordsets as input parameter also returns recordsets as output.
I have a requirement to do stock taking for all order items of one Order number in one single query execution (to avoid row by row basis).
From the post in the forum I know that a function can return recordsets / query result using REF CURSOR or pipelined table function.
My question is : how to pass the recordsets as input parameter to that function ?
(because I could have 75 rows item in one order number)
Below is the DDL and the query :
create table stocks (Product char(4), Warehouse char(5), expireddate date, qty_available number)
insert into stocks values('P001', 'WH001', '01-dec-2006', 30)
insert into stocks values('P001', 'WH002', '01-dec-2006', 50)
insert into stocks values('P001', 'WH002', '01-jan-2007', 50 )
insert into stocks values('P001', 'WH001', '01-Mar-2007', 150)
insert into stocks values('P002', 'WH003', '01-dec-2006', 25)
insert into stocks values('P002', 'WH003', '15-Jan-2007', 50)
insert into stocks values('P002', 'WH003', '01-Mar-2007', 75)
insert into stocks values('P003', 'WH001', '01-dec-2006', 30)
insert into stocks values('P003', 'WH002', '15-Jan-2007', 40)
insert into stocks values('P003', 'WH003', '01-Mar-2007', 50)
CREATE TABLE Order_Detail (PRODUCT_ORD CHAR(4), QTY_ORD number, Priority_WH CHAR(5) )
INSERT INTO Order_Detail VALUES ('P001', 75, 'WH003') // previously 'WH002'
INSERT INTO Order_Detail VALUES ('P002', 45, 'WH002')
INSERT INTO Order_Detail VALUES ('P003', 55, NULL)
The query for stock taking :
select product,warehouse,expireddate, least(qty_available-(sm - qty_ord),qty_available) qty
from ( select product,warehouse,expireddate,qty_available,qty_ord, sum(qty_available) over(partition by product order by s.product,expireddate,decode(warehouse,priority_wh,0,1),warehouse ) sm
from stocks s,order_detail o
where s.product = o.product_ord order by s.product,expireddate,decode(warehouse,priority_wh,0,1) )
where (sm - qty_ord) < qty_available

Hi,
This my requirement :
I have (simplified)Order_Detail as below :
CREATE TABLE Order_Detail (PRODUCT_ORD CHAR(4), QTY_ORD number, Priority_WH CHAR(5) )
INSERT INTO Order_Detail VALUES ('P001', 75, 'WH003') // previously 'WH002'
INSERT INTO Order_Detail VALUES ('P002', 45, 'WH002')
INSERT INTO Order_Detail VALUES ('P003', 55, NULL)
Then I want to do stock taking from my STOCK table (described on my first post on this thread)
create table stocks (Product char(4), Warehouse char(5), expireddate date, qty_available number)
The rule is : The stok taking is on First In First Out basis, on expireddate.
And I want to do it in single query.
I want to make this a Function / Stored Procedure so that other transaction can also make use of this query.
That is why I need to pass the 3 rows oy mr Order_Detail above, do the query, and return the result.
Then INSERT the result into ORDER_DETAIL_PER_EXPIRED_DATE table.
I hope this clear my requirement, is this possible ?
Thank you,
