--*******************************************************
Notice a couple of things.
1) the use of a cursor parameter i.e.:pvar
2) it is (cast(:pvar as list_table)) not (cast(:pvar) as list_table)
and most of all you need to use a "TABLE OF OBJECTs" as your collection in
order to use the TABLE function.
CREATE TYPE list_object AS OBJECT (
list_value VARCHAR2 (35)
);
CREATE TYPE list_table AS TABLE OF list_object;
not sure if this will all work in 8.1.7 but it should.,
As a final note, you are returning a ref cursor. I would have simply
returned the Object Table. Maybe your assignment required you to use a
ref_cursor?
