Can a PL/SQL table Object Type be used in a VO?

Question

Hi,
Is it possible to use a PL/SQL table object type to provide data to a View Object? In short, I would like to be able to do something like this:
1. Create record object:
CREATE OR REPLACE TYPE xx_rec_type AS OBJECT
(xxid NUMBER,
xxdesc varchar2(10),
xxcost number...);
2. Create table object:
CREATE OR REPLACE TYPE xx_tbl_type AS TABLE OF xx_rec_type;
3. Declare and populate the object in PL/SQL package:
xx_tbl xx_tbl_type;
xx_tbl(i).xxid := 1;
xx_tbl(i).xxdesc := 'XXX';
xx_tbl(i).xxcost := 10.00;
4. Create a View Object as:
SELECT * FROM xx_tbl
Is it even possible to access xx_tbl from View Object? If anyone has done something like this, please do share.
TIA
Alka

A PL/SQL procedure can exist in Oracle DB, in TimesTen, or in both. You control that by where you create the procedure. Procedures that exist in Oracle can really only be called in Oracle and can only access data in Oracle. Procedures that exist in TimesTen can only be called in TimesTen and can only access data in TimesTen. There is a limited capability, using the TimesTen PassThrough capability to call PL/SQL procedures located in Oracle, from Timesten, and for Timesten PL/SQL procedures to access data in Oracle. Using PassThrough does have some overhead.
