How I can change this query

Question

How I can change this query, I got it from someone on the list, and it works just fine, Thank you! but I can not hardcode the data, the data is actually in a repiting table
SARAPPD_PIDM, SARAPPD_TERM_CODE_ENTRY, SARAPPD_APPL_NO 1 SARAPPD_SEQ_NO
We can have a person with one record another one with two or three, we just don't know, each record have a sequence number SARAPPD_SEQ_NO
this SARAPPD_PIDM = 2232040 with will a paramater pass to the function (SARAPPD_PIDM = p_pidm)
excuse my ignorance, but I just don't have experience with this kind of queries..
with t as ( -- sample data
    select 2232040     SARAPPD_PIDM,  200990 SARAPPD_TERM_CODE_ENTRY, 1 SARAPPD_APPL_NO, 1 SARAPPD_SEQ_NO,   to_date('12/03/2008','mm/dd/yyyy') sARAPPD_APDC_DATE,  'S*'     SARAPPD_APDC_CODE from dual union all
    select 2232040     ,200990     ,1    ,2     ,to_date('12/08/2008','mm/dd/yyyy'),     'D1' from dual union all
    select 2232040     ,200990     ,1    ,3    ,to_date('03/18/2009','mm/dd/yyyy'),  'S*'  from dual union all
    select 2232040    ,200990     ,1    ,4     ,to_date('03/29/2009','mm/dd/yyyy')     ,'WL' from dual union all
    select 2232040    ,200990     ,1    ,4     ,to_date('03/27/2009','mm/dd/yyyy')     ,'WL' from dual
    ) -- end sample data
    SELECT * FROM (
    SELECT
   A.SARAPPD_PIDM,
   A.SARAPPD_APDC_CODE,
   A.sarappd_apdc_date,
   ROW_NUMBER() OVER (PARTITION BY SARAPPD_PIDM, SARAPPD_TERM_CODE_ENTRY ORDER BY SARAPPD_APDC_DATE
   DESC) row_num
   ,lead (SARAPPD_APDC_DATE,1) over (ORDER BY SARAPPD_APDC_DATE) AS next_date
   FROM t A
   where
    SARAPPD_PIDM = 2232040
     AND sarappd_apdc_code IN ('SA', 'FA', 'S-', 'F-', 'RF', 'F*','AD', 'W-', 'R2', 'S*', 'HF', 'WL','HD', 'R1', 'HS', 'D2', 'W+')
   where  next_date >= to_date('3/27/2009','mm/dd/yyyy');Edited by: user648177 on May 1, 2009 8:52 AM

Answer 1

Thank you
I am getting this result
SARAPPD_PIDM     SARAPPD_APDC_CODE              SARAPPD_APDC_DATE     SARADAP_ADMT_CODE     ROW_NUM               NEXT_DATE
2232040                                   S*            12/03/2008 16:30:45     D1                                    3                  03/18/2009 08:58:06
2232040                                   S*            03/18/2009 08:58:06     D1                                      2                 03/21/2009 13:53:23I only want to retrieve the one with the max date ( 03/18/2009 08:58:06)
I try to add the
and SARAPPD_SEQ_NO = (select max(b.SARAPPD_SEQ_NO)
                               from SARAPPD b
                               where SARAPPD_pidm = b.SARAPPD_pidm)
{code}
{code}
but it did not work
{code}
SELECT *
  FROM (SELECT A.SARAPPD_PIDM,
               A.SARAPPD_APDC_CODE,
               A.sarappd_apdc_date,
               saradap_admt_code,
               ROW_NUMBER() OVER(PARTITION BY SARAPPD_PIDM, SARAPPD_TERM_CODE_ENTRY ORDER BY SARAPPD_APDC_DATE DESC) row_num,
               lead(SARAPPD_APDC_DATE, 1) over(ORDER BY SARAPPD_APDC_DATE) AS next_date
          FROM saturn.sarappd A, SARADAP
         where SARAPPD_PIDM = 2232040
           and SARADAP_PIDM = SARAPPD_PIDM
           AND saradap_term_code_entry = SARAPPD_TERM_CODE_ENTRY
           AND SARADAP_APPL_NO = A.SARAPPD_APPL_NO
           --         and SARAPPD_SEQ_NO = (select max(b.SARAPPD_SEQ_NO)
            --                    from SARAPPD b
            --                    where SARAPPD_pidm = b.SARAPPD_pidm)
           AND sarappd_apdc_code IN
               ('SA', 'FA', 'S-', 'F-', 'RF', 'F*', 'AD', 'W-', 'R2', 'S*', 'HF', 'WL', 'HD', 'R1', 'HS', 'D2', 'W+'))
Where next_date <=       saturn_midd.utlq.f_get_adm_freeze_date(saradap_admt_code)
{code}
i now that if I add and row_num=2 it will work, but this is just an example I don't know the row_num of all the records
