select rows from selected rows.

Question

I have following procedure syntax working :

//p_type is a varchar which has some value to be comapred. and USER_ID is a int which holds a integer value. i want cond1 OR con2 OR con3 to be worked only for condA OR condB.. i mean i want this result to be displayed only for admin or matched user id for id of tab_2. i think this is not the correct one. because it work for both OR statements . can anyone plz help.. thanx in advance 

select count(1) from
from
(
  select id,
  CASE
  when a >= 0 and a <= 30 then 'one'    
  when a >= 31 and a <= 60  then 'two'    
  when a >= 61 and a <= 90  then 'three'    
  else 'NO'
  END
  FROM tabel_1 t
  Where
  (
        (
           TO_CHAR(t.aDate, 'YYYYMMDD') BETWEEN TO_CHAR(pFrom_Date, 'YYYYMMDD') AND    
                TO_CHAR(pTo_Date, 'YYYYMMDD')
