To whom it might interest - "bulk" changes to the apex repository

Question

For those who might be interested in methods for "bulk" changing the apex repository, especially for medium large applications, i wrote a few queries that may come in handy for common problems like :
- "how to change template on all labels currently set to "Optional"?
- "how to quickly delete a region with a given name from multiple pages in one shot?"
- "how to check if there are items or buttons attached to a region?"
and stuff like that...
The list of queries that i initially supplied is supposed to grow in the future.
Of course this kind of practice is absolutely unsupported, officially discouraged, so, use at your own risk.

Hi Flavio
Your post didn't appear to set session state anywhere, which tends to screw things up.
ie. your objects "disappear" from your workspace and get reassigned to flow_id 0.
I always do the following before any changes:
declare
l_flow_id number := 101; /** set to match application */
l_company_id number := 1203342054321505; /** set to match application */
l_user varchar2(30) := 'MARK'; /** set to match application */
l_sgid number := wwv_flow.get_current_flow_sgid(l_flow_id,l_company_id);
l_csize number := 12;
begin
-- set Apex context
apex_application.g_user := l_user;
wwv_flow.g_flow_id := l_flow_id;
if l_sgid is not null then
wwv_flow_api.set_security_group_id(p_security_group_id=>l_sgid);
else
raise_application_error(-20000,'Security group ID not found - must fix before can continue.');
end if;
/*** now do your changes ***/
end;
