Resetting the number value after a given date.

Question

Hi everyone I was just wondering if this piece of sql will work in resetting the number for days_off to 0 when the date is July 7th. Afterwards I want it to continue doing the SUM of days, just start anew after July 7th (props to Pollywog who gave me the original script which I then butchered and modified, which is why I am asking if it's any good).
WITH t AS (  SELECT id,
                    MAX (strt) strt,
                    MAX (finish) finish,
                    SUM (dys) days_off
               FROM (SELECT id,
                            strt,
                            finish,
                            CASE
                               WHEN TO_CHAR (dy, 'day') LIKE 'saturday%' THEN 0
                               WHEN TO_CHAR (dy, 'day') LIKE 'sunday%' THEN 0
                               ELSE 1
                            END
                               dys
                       FROM vacations
                     MODEL
                        PARTITION BY (ID id)
                        DIMENSION BY (0 d)
                        MEASURES (POCETAK strt, KRAJ finish, POCETAK dy)
                        RULES
                           (dy [FOR d FROM 1 TO finish[0] - strt[0] INCREMENT 1] =
                                 (NVL (dy[CV () - 1], dy[CV ()]) + 1)))
           GROUP BY id
           ORDER BY id)
SELECT t.id,
       t.strt,
       t.finish,
       t.days_off,
       vacations.korisnik,
       SUM (
          CASE
             WHEN SYSDATE != TO_DATE ('01/07/2011', 'dd/mm/yyyy') THEN days_off
             ELSE 0
          END)
       OVER (PARTITION BY vacations.korisnik ORDER BY t.id)
          this_years_running_total
  FROM t, vacations
WHERE t.id = vacations.id

Hi,
sysdate will come with a time factor so you will never reach the equality, you have to change that:
WHEN to_char(SYSDATE,'dd/mm/yyyy') != '01/07/2011' THEN days_offHerald ten Dam
