unfortunately , I work at oracle .
instead of TOP , oracle use "where rownum" condition.

If I use

SQL

SELECT a.il_kod
                       FROM m_m_adres a
                      WHERE a.hesap_no = p_hesap_no
                        AND a.adres_kod LIKE v_adres_kod_like
                        AND a.adres_ulke_kod = 169
                        AND a.il_kod IS NOT NULL
                         where rownum <= 1 ORDER BY a.tarih,a.adres_kod

this sql execute "where condition" firstly and then "order by" , and this is not my need .
