ORA-01403: no data found for default value

Question

I have the following pl/sql function body for setting the default value of a select list.
DECLARE
selected VARCHAR2(100);
BEGIN
select person_id into selected from ht_people
where :app_user=flow_user;
RETURN selected ;
END;
It works perfectly until the user who is logged in is not on the list and then I get:
ORA-01403: no data found
ERR-9131 Error in PLSQL function body for item default code, item=P7_IDENTIFIED_BY
Is there an item property I can set to handle this or must this be done in PL/SQL?

Answer 1

This will throw no error if user not found:
DECLARE
   selected   VARCHAR2 (100);
BEGIN
   FOR c IN (SELECT person_id
               FROM ht_people
              WHERE :app_user = flow_user)
   LOOP
      selected := c.person_id;
   END LOOP;
   RETURN selected;
