Ref cursor in select statement

Question

I am not sure this is the right forum, but I got no reply from the OTN Sample.
How do I call a function from a select
statement ?
The function returns a ref cursor.
Here is the function definition:
FUNCTION get_priority_code_list
(p_language_id IN VARCHAR2)
RETURN RefCur
IS
rcur RefCur;
BEGIN
OPEN rcur FOR SELECT
priority_code "priority_code_menu",
priority_code_desc "priority_code_menu_desc"
FROM
prio_desc
WHERE
language_id = p_language_id;
RETURN rcur;
END;
I would like to wrap a SELECT statement
around the function and have the same result
as running the SELECT statement directly.
Of course it does not seem logical here to
use a function, but in fact I want the
function to do more than just a select....
I tried the syntax
SELECT package.function(param) FROM dual;
but that does not work...
or
SELECT * FROM package.function(param);
but that does not work either....
any idea ?
Tks.

Answer 1

I have a stored function that returns a ref cursor and I want to use it in select
I tried the following code
for example if the ref cursor returned rows of varchar2
I will define an object
CREATE TYPE myType as OBJECT( doc_type VARCHAR2(256));
created a type as a table of myType
create or replace type myTable as table of myType;
If I write a select statement like below
select * from TABLE(CAST(function_name() AS myTable))
ERROR at line 1:
ORA-00932: inconsistent datatypes: expected - got CURSER
I get this error
Can anyone give any clue why this does throw an error or if there is a second way to do this,
