Dynamically change number of columns in report

Question

all,
I am trying to change the number of columns in a report dynamically as in this sample(http://actionet.homelinux.net/htmldb/f?p=LSPDEMO:60:11041263091189::NO:::) , can somebody who has this code kindly send it to me or make reference...i'll appreciate

Answer 1

But Howards solution is easier to follow and works perfectly with a shuttle.
Define a function like this:
create or replace FUNCTION item_in_list(p_num IN NUMBER, p_shuttle_name in VARCHAR2)
RETURN NUMBER
IS
    l_vc_arr2   APEX_APPLICATION_GLOBAL.VC_ARR2;
    TYPE number_list is TABLE OF NUMBER;
    num_list number_list := number_list();
    x_ret NUMBER;
BEGIN
    /* checks if p_num exists in the colon delimited list p_shuttle_name */
        l_vc_arr2 := APEX_UTIL.STRING_TO_TABLE(p_shuttle_name);
        FOR i IN 1..l_vc_arr2.COUNT LOOP
            num_list.EXTEND;
            num_list(i):= CAST(l_vc_arr2(i) AS NUMBER);
        END LOOP;
        IF p_num MEMBER OF num_list then
            return 1;
        else
            return 0;
        end if;
END;
And then for every column put a condition (Function returning boolean) like this:
begin
if item_in_list(1, : p10_shuttle) = 1 then
return true;
else
return false;
end if;
end;
where 1 in my case is the return lov value.
This is if your shuttle's return value is numeric and display value is varchar2. If both are varchar2 use instr as Howard suggested.
Its probably not as fancy as the Jquery one but gets the job done.
