Auto Query Form on Page

Question

Hi,
I'd like to have a form on a page and when the user navigates to that page I'd like the form to pick up a session variable and put it in a field on the form and run a query. So effectively auto querying a form.
I've seen it done before but cant seem to find it again.
I think that it was done by putting some PL/SQL in the 'before displaying the page' area of the additional PL/SQL section. The code would load the session, get the value, set the field value and somehow make it run a query. doQuery doesn't work here.
Any help with this would be great.
Thaks,
Michelle

I have a similar problem. In particular:
There is a private form (named MOD_ANAGRAFE_DITTA) based on a database table. The URL to
run this form is
https://portal.websanity.it/pls/portal/PORTAL.wwa_app_module.new_instance?p_moduleid=6994683181.
There is also a page from which the MOD_ANAGRAFE_DITTA form is called. To do this, a URL element was added to the page in whi
ch the above url was specified.
Based on some of the OID attributes of the user who connects to the page, when the user runs the form, the form would have to show only the record that satisfies those attributes.
To do this the following code was entered in the 'BEFORE DISPLAY PAGE' section of the FORMs Wizard:
declare
scopo varchar2(50);
user varchar2(200) := portal.wwctx_api.get_user;
BEGIN
select attrvalue into scopo
from ods.ct_scope
where entryid in (select entryid
from ods.ct_uid
where attrvalue=lower(user));
p_session.set_value(p_block_name => 'DEFAULT',
p_attribute_name => 'A_ID',
p_value => to_number(substr(scopo,1,1)));
p_session.set_value(p_block_name => 'DEFAULT',
p_attribute_name => 'A_SEDE',
p_value => substr(scopo,5));
p_session.set_value(p_block_name => 'DEFAULT',
p_attribute_name => '_CALLED_FROM_LINK',
p_value => 'SEDE');
PORTAL.wwa_api_module_event.do_event
('DEFAULT','QUERY_BOTTOM',1,'ON_CLICK',True,'',p_session);
END;
where scope is the OID attribute of user; ID and SEDE are the two table columns must to be filtered
The code to auto-query a form doesn't work as it should. The form shows all the table records. .
Perhaps the attribute used to do the query is not a session variable?
How can this be resolved?
