Forward declaration concept

Question

hi,
i have a package
CREATE OR REPLACE PACKAGE BODY pkgemp AS
FUNCTION fNeedsCpeReview(
p_order_id IN VARCHAR2 DEFAULT NULL)
RETURN product_info_tbl
is
CURSOR csr_ord_control IS
SELECT action_cd
FROM ord_control
WHERE order_id = l_order_id;
begin
select * from abc where enum=1234;
execute immediate create table abc(
enum number);
END pkgemp;
-- please forget abt the function and cursor.
-- the table 'abc' is not present in the DB
-- so we cannot execute select statement and compilation error even though we are creatign that table after 'select' statement
-- we need to do forward declarartion.
my question is how do we do a forward declaration for creating a table ?

Hi,
Creating tables in procedures is rarely necessary in Oracle.
Describe what you're trying to do, and someone will suggest a good way to do it. Many people have used global temporary tables where they thought creating a table on the fly was necessary.
If you really do have to use table (abc) that may not exist at compile time, or if abc may be dropped and recreated after the procedure is compiled, then do everything that involves abc using dynamic SQL.
Remember that EXECUTE IMMEDIATE works on strings, so
execute immediate create table abc(
enum number);is incorrect, but
execute immediate 'create table abc(
                                   enum number)';will work.
