Open a cursor containing a nested table?

Question

I have created a table with several nested tables by following the examples in: http://otn.oracle.com/docs/products/oracle8/doc_index.htm
I am now trying to query one of these nested tables using the techniques that are described.
The two techniques are (page 31 of above reference):
(1) "Flattened" query.
(2) Nested cursor
Both of these techniques work by simple SQL queries in SQl*Plus.
However, I get compilation errors when using identical queries when trying to open and return a cursor in a stored procedure.
Can you please help? Is this supported in 8.1.7?
Is there a better way to query and return data using OO4O to a windows client program?
If necessary, I would be glad to provide code samples.
Thank you,

Answer 1

Here is a copy of my test code for the question that I posted. Any help on how I can get nested table data back to a windows client would be greatly apreciated.
Thank you.

--DDL.
--Original table.
CREATE TABLE MY_TABLE(
MY_KEY INTEGER,
MY_DATA VARCHAR2(2000));
--Basic Object types.
CREATE TYPE MY_NUMERIC_OBJTYP AS OBJECT(
SEQUENCE INTEGER,
DATUM NUMBER);
CREATE TYPE MY_TEXT_OBJTYP AS OBJECT(
SEQUENCE INTEGER,
DATUM VARCHAR2(255));
--Table type. Table of basic objects.
CREATE TYPE MY_NUMERIC_TABTYP AS TABLE OF MY_NUMERIC_OBJTYP;
CREATE TYPE MY_TEXT_TABTYP AS TABLE OF MY_TEXT_OBJTYP;
--Add nested tables to original table.
ALTER TABLE MY_TABLE ADD(
MY_NUMERIC_NTAB MY_NUMERIC_TABTYP)
NESTED TABLE MY_NUMERIC_NTAB STORE AS MY_NUMERIC_TABLE;
ALTER TABLE MY_TABLE ADD(
MY_TEXT_NTAB MY_TEXT_TABTYP)
NESTED TABLE MY_TEXT_NTAB STORE AS MY_TEXT_TABLE;
--Insert test data in the main, unnested table.
INSERT INTO MY_TABLE(
MY_KEY, MY_DATA
)VALUES(
1001, 'RECORD-1001');
COMMIT;
--Create the actual nested tables.
UPDATE MY_TABLE SET
MY_NUMERIC_NTAB = MY_NUMERIC_TABTYP();
UPDATE MY_TABLE SET
MY_TEXT_NTAB = MY_TEXT_TABTYP();
COMMIT;
--Insert test data into the nested tables.
INSERT INTO TABLE(
SELECT X.MY_NUMERIC_NTAB
FROM MY_TABLE X
WHERE MY_KEY = 1001
)VALUES(
1,901);
INSERT INTO TABLE(
SELECT X.MY_NUMERIC_NTAB
FROM MY_TABLE X
WHERE MY_KEY = 1001
)VALUES(
2,902);
INSERT INTO TABLE(
SELECT X.MY_NUMERIC_NTAB
FROM MY_TABLE X
WHERE MY_KEY = 1001
)VALUES(
3,903);
INSERT INTO TABLE(
SELECT X.MY_TEXT_NTAB
FROM MY_TABLE X
WHERE MY_KEY = 1001
)VALUES(
1,'ONE');
COMMIT;
BOTH OF THESE QUERYS WORK WHEN ENTERED IN SQL*PLUS.
