Dynamically change table selecting from

Question

in 3.2 on 11g database is there a way to dynamically change the table used in a select statement for an interactive report? I have a series of similar tables, one for each month of the year. I want to click a month on one page and bring up a report from the table for that month. I want to use one page for this report and have all links from previous page link to the same page, just different result based on what month was clicked.
I know I could just setup 12 different reports and conditionally display each region based on a value passed to the that page, but I'd prefer to only create one page & one report on that page.
Thanks for any ideas or solutions.

Your function will have the code dynamically built.. What you do is you build your sql and pass in the table name and any other items that will change based upon your requirements..
here is an example...
function inventory_report (p_State IN VARCHAR2) RETURN VARCHAR2 IS
declare
  q varchar2(4000);
begin
  q:='   select p.category, ';
  q:=q||'       p.product_name, ';
  q:=q||'       p.quantity, ';
  q:=q||'       p.unit_price '; 
-- Here is where we substitute the passed in state name for the data table we extract data from
  q:=q||'  from ' || V('p_State') || ' p, ';
  q:=q||' where p.product_quantity > 0 ';
  return q;
end;Thank you,
