Cannot create view with parameter bindings

Question

Hi, I'm trying to create this view in SQLPlus:
SELECT order_no, SUM(cut_qty),
SUM(received_qty)
FROM (
SELECT order_no, cut.dated, DECODE(cut.bimetallic, 'F', cut.quantity, cut.quantity/2) cut_qty,0 AS received_qty
FROM cut_shop_orders_dated cut
WHERE cut.dated BETWEEN TO_DATE('&date1','DD/MM/YYYY') AND TO_DATE('&date2','DD/MM/YYYY')
UNION
(SELECT order_no, rec.dated, 0, rec.quantity
FROM received_shop_orders_dated rec
WHERE rec.dated BETWEEN TO_DATE('&date3','DD/MM/YYYY') AND TO_DATE('&date4','DD/MM/YYYY')))
GROUP BY order_no
The problem is that sqlplus asks me for the parameter values and then creates it with these values as literal dates in the to_date function, those not asking for parameter values in runtime.
How can I create it using parameters with no values at design time?
Thanks.
Leandro.

Answer 1

if you want something like :
select * from emp $where_clause;
you can write a procedure with parameter and run it as dynamic sql for example
create or replace procedure pr1 ( p_where   varchar2) is
begin
  execute immediate 'create or replace view view_name as select * from emp '|| p_where;
end pr1;
/then run it on sql*plus
SQL> exec pr1('where deptno = 10');
make sure you give yourself "create any view" rights explicitly.
