Ampersand substitution in create or replace procedure statement

Question

Hi Guys,
I wonder why my ampersand substitution does not work in a create or replace stored procedure statement.
CREATE OR REPLACE PROCEDURE UPDATE_DIM_SALES AS
UNDEFINE DimSales;
UNDEFINE FactTable;
DEFINE DimSales = 'TESTTAB';
DEFINE FactTable = myfact;
BEGIN
Error(5,20): PLS-00103: Encountered the symbol "=" when expecting one of the following: := . ( @ % ; not null range default character
If I then assign the value with := I get the error "invalid table" later on for the INSERT statemnt:
CREATE OR REPLACE PROCEDURE UPDATE_DIM_SALES AS
UNDEFINE DimSales;
UNDEFINE FactTable;
DEFINE DimSales := 'x2';
DEFINE FactTable := 'x1';
BEGIN
INSERT INTO &DimSales  (column1, column2,...)
Why does ampersand substitution not work within a stored procedure?

Hi,
Thanks for the suggestion.
The IF---ELSE Logic I have to write is quite complex.
I dont think joins will not do the trick and limiting the collection size to smaller than 4000 seems not very practical. there
is no poin using a collection if I have to use X amout of them.
UNDEFINE DimSALES;
UNDEFINE FactTable;
DEFINE DimSALES = 'TESTTAB';
DEFINE FactTable = 'testfact';
--Collect all distinct SELLERNr into materialized views
CREATE MATERIALIZED VIEW v1 AS select distinct SELLERnr from &FactTable;
CREATE MATERIALIZED VIEW v2 AS select distinct SELLER_ID from &DimSALES;
DECLARE
v_SELLERNr VarChar(9);
CURSOR v1_cursor IS Select * from v1;
l_exists INTEGER;
BEGIN
OPEN v1_cursor;
LOOP
FETCH v1_cursor INTO v_SELLERNr;
EXIT WHEN v1_cursor%NOTFOUND;
SELECT COUNT(*) INTO l_exists FROM v2 WHERE SELLER_id =v_SELLERNr AND ROWNUM = 1;
IF l_exists <> 1 THEN
INSERT INTO &DimSALES (K_SALES,REG,BVL,DS, VS,RS,SELLER_ID,VK,VALID_FROM)
(SELECT SEQ_DIM_SALES.NEXTVAL ,REG, BVL,DS, VS,RS,SELLERNR,VK,sysdate from &FactTable where SELLERNR =v_SELLERNr);
commit;
ELSE
--Update old combination(s), invalidate (DATE)
UPDATE &DimSALES SET VALID_TO = SYSDATE -1 WHERE REG||BVL||DS||VS||RS||SELLERNR||VK IN(
--In case the SELLER and combinations exists and differs from what is in the dimension then invalidate old combinations and insert new ones
SELECT * FROM(
SELECT REG||BVL||DS||VS||RS||SELLERNR||VK WHERE SELLERNR = v_SELLERNr FROM &FactTable;
MINUS
SELECT REG||BVL||DS||VS||RS||SELLERNR||VK WHERE SELLERNR = v_SELLERNr FROM &DimSALES;)

END IF;
END LOOP;
CLOSE v1_cursor;

DROP MATERIALIZED VIEW v1;
DROP MATERIALIZED VIEW v2;
