How to get the plsql table data into output cursor

Question

Hi,
Could anybody please help me.
Below is an example of the scenario..
CREATE OR REPLACE PACKAGE chck IS
PROCEDURE getdata(dept_no IN VARCHAR2,oc_result_cursor OUT sys_REFCURSOR);
TYPE get_rec is record (ename varchar2(20),
eno number(12));
TYPE t_recs IS TABLE OF get_rec INDEX BY BINARY_INTEGER;
emp_tab t_recs;
END chck;
CREATE OR REPLACE PACKAGE BODY chck AS
PROCEDURE getdata(dept_no IN VARCHAR2,oc_result_cursor OUT sys_REFCURSOR)
is
BEGIN
select ename, eno
bulk collect into emp_tab
from emp;
open oc_result_cursor for select * from table(emp_tab); -- I believe something is wrong here ....
END;
END chck;
the above package is giving me an error:
LINE/COL ERROR
10/29 PL/SQL: SQL Statement ignored
10/43 PL/SQL: ORA-22905: cannot access rows from a non-nested table
item
let me know what needs to be changed
Thanks
Manju

It is nothing at all like a table. It cannot be indexed, partitioned, cluster, etc. It does not exist in the SQL engine as an object that can be referenced. It resides in expensive PGA memory and needs to be copied (lock, stock and barrel) to the SQL engine as a bind variable.
It is an extremely primitive structure - and should never be confused as being just like a table.
Its use in SQL statements is also an exception to the rule. Sound and valid technical reasons need to justify why one want to push a PL/SQL array to the SQL engine to run SELECT 's against it.
