Output different data based on user select

Question

Hi everyone,
Quick question, I would like to output different report columns based on user select, eg., users would be presented with two choices in a radiobutton list, eg., 1 and 2.
I have query results that contain columns A, B, C, D, E, F, G.
If user selects 1 then the output should be columns A, B, C, D, E.
If user selects 2 then the output should be columns A, B, C, F, G.
I am sure this is possible and easy? If so, what topic should I be reading/searching internet on?
Please advise.
Thanks!

I would say that this is most often something that your user interface should be dealing with (i.e. which columns should be shown).
There is no way to do that in SQL.
In PL/SQL it is a simple situation of creating two cursors and simply deciding which one to open.
<pre>declare
l_cur sys_refcursor;
begin
if :user_selection = 1 then
open l_cur for select A, B, C, D, E from tbl;
else
open l_cur for select A, B, C, F, G from tbl;
end if;
-- use the cursor
close l_cur; -- or return to user interface
end;
/</pre>
Hope this helps.
