Buliding a SELECT in PSP using fields from html form

Question

Hi everyone, first of all forgive me my poor english.
I'm making "CV Base" in PSP as a school project. And I've got a search html form like this (simple version):
select list: Profession
text field: Age
And my question is... How to build a select in psp which will parse only given parameters? For example. I'm looking for C Programmer in any age so i select C Pogrammer from the list and leave afe field blank. So the SELECT should be sth like this: select * from Person where Profession like 'C Programmer'; But in another search i need a programmer who is 25 years old... So select has one more WHERE... I'm sure You all know what I mean
Please help me.

<%@ plsql parameter="f_wyk" type="varchar2" default="NULL" %>
<%! sel_str varchar2(1000) := 'SELECT imie, nazwisko, wiek, ulica, nr_domu, nr_lokalu, kod_pocz, miasto, nazwa_woj FROM Uczelnia ucz, Stanowisko stan, Jezyk jez, Wojewodztwo woj, Wyksztalcenie wyk, Adres adr, Osoba os, os_wyk ow, os_jez oj, os_sta ost, os_ucz ou WHERE nazwa_wyk LIKE :1 ...
<% OPEN cur FOR sel_str USING 'pod%'; %>
<% LOOP %>
<% FETCH cur INTO rosoba; %>
<% EXIT WHEN cur%NOTFOUND; %>
<%= rosoba.imie %>
<% END LOOP; %>
<% CLOSE cur; %>
