Some basic form submission questions

Question

Hello,
1. On page 1, I've created a form which contains only one text field (P1_USERNAME) and a submit button which leads to Page 2. On page 2, I can't seem to access the value of :P1_USERNAME. From Page 2, when I press the 'Session' button, it shows P1_USERNAME with the correct value under Session State.
What am I doing wrong?
2. Page 2 is a User Profile page, which needs to display various information about a user whose username was entered on Page 1. Is it possible to run only one query and fill the disabled text fields on Page 2 from that one query instead of running a separate SELECT queries for each field?
Thanks :)

Answer 1

1) In what context can you not access the value of P1_USERNAME? Describe how you trying to access its value. If you see the item and its value in the session state, it is definitely accessible from page 2.
2) To display the user's current profile just create a SQL report region with the SELECT statement's WHERE referring to P1_USERNAME. Something like:
  SELECT first_name, last_name, ...
    FROM user_profile
   WHERE username = :P1_USERNAMEMike
