Between clause with DECODE function.

Question

Hi All,
I have one table which has object, date and quantity columns, Now based on date range I can find out the objects and quantity but the question is: I want a query which returns all the objects and should show quantity 0(zero or null) for those objects which don't falls under that date range. So I thought to use a decode function but it only uses the relational operation, I thought something like this but it's wrong,
select object,decode(created_date,BETWEEN '01/01/2008' TO '08/01/2008',quantity,0) from table;
Does anyone have any idea how can I make this work in single sql statement?
Thanks for your help.
