How can change my code without using if else in procedure

Question

Hai ,
I have wrote code like this
if RPTFORMNTH='M' then
SELECT coalesce(SUM(IN_RWEEKS),0),
INTO C2_COL1
FROM HS_CASEDTA_DTLS_TB
WHERE UPPER(VR_HAUNM) like NVL(case when HAUNM='0' then null else UPPER(HAUNM) END , UPPER(VR_HAUNM))||'%'
AND IN_ULBOBJID=ULBOBJID AND CH_FLAG!='D'
AND VR_RPTFORMNTH=VR_RPTFORMNTH
AND IN_YEAR=IN_YEAR;
ELSE
SELECT
coalesce(SUM(IN_RWEEKS),0),
INTO C2_COL1
FROM HS_CASEDTA_DTLS_TB
WHERE UPPER(VR_HAUNM) like NVL(case when HAUNM='0' then null else UPPER(HAUNM) END , UPPER(VR_HAUNM))||'%'
AND IN_ULBOBJID=ULBOBJID AND CH_FLAG!='D'
AND
TO_DATE(('01/'||VR_RPTFORMNTH||'/'||IN_YEAR),'DD/MM/YYYY')
BETWEEN to_date('04/' || to_char(RPTYEAR-1),'MM/YY')
AND add_months(to_date(RPTFORMNTH || to_char(RPTYEAR),'MonYYYY'),1)-1;
END IF;
My query is without using if else and replicate data in if and else how can i modify code.Observe that only where condition i want changes that's why i used if else without that how can i modify where clause with that two conditions.Please give me guidance.

hi,
I think you want your condition to change inside the where clause so you could have only one select statement. If that is so try this:
SELECT coalesce(SUM(IN_RWEEKS),0),
INTO   C2_COL1
FROM   HS_CASEDTA_DTLS_TB
WHERE  1 = CASE WHEN RPTFORMNTH='M' THEN
                CASE WHEN UPPER(VR_HAUNM) like NVL(case when HAUNM='0' then null else UPPER(HAUNM) END , UPPER(VR_HAUNM))||'%'
                          AND IN_ULBOBJID=ULBOBJID AND CH_FLAG!='D'
                          AND VR_RPTFORMNTH=VR_RPTFORMNTH
                          AND IN_YEAR=IN_YEAR
               THEN 1
                     ELSE 0
                END
           ELSE --  RPTFORMNTH !='M'
                CASE WHEN UPPER(VR_HAUNM) like NVL(case when HAUNM='0' then null else UPPER(HAUNM) END , UPPER(VR_HAUNM))||'%'
                          AND IN_ULBOBJID=ULBOBJID AND CH_FLAG!='D'
                          AND TO_DATE(('01/'||VR_RPTFORMNTH||'/'||IN_YEAR),'DD/MM/YYYY')
                          BETWEEN to_date('04/' || to_char(RPTYEAR-1),'MM/YY')
                          AND add_months(to_date(RPTFORMNTH || to_char(RPTYEAR),'MonYYYY'),1)-1
                     THEN 1
                     ELSE 0
                END

hi Are, after belatedly reading Rob's post, I think his post is better. I was only looking at your highlighted code, but he took the most common conditions inside the where clause.
