Ada banyak hal yang tidak terkatakan. Saya harap Anda menerima persyaratan yang lebih jelas dalam pekerjaan sehari-hari Anda ... Bagaimanapun, ini adalah simulasi situasi Anda. Ini didasarkan pada asumsi bahwa hari dengan data (satu per minggu) adalah sama pada tahun 2007 seperti pada tahun 2008:
SQL> create table lnd_wkly_plan_rx_summary (pd_end_dt,nrx_cnt)
2 as
3 select date '2008-09-07', 100000 from dual union all
4 select date '2008-09-07', 536619.92 from dual union all
5 select date '2008-09-14', 698082.03 from dual union all
6 select date '2008-09-21', 403604.59 from dual union all
7 select date '2008-09-21', 200000 from dual union all
8 select date '2008-09-21', 100000 from dual union all
9 select date '2008-09-28', 702457.36 from dual union all
10 select date '2007-09-07', 400000 from dual union all
11 select date '2007-09-14', 450000 from dual union all
12 select date '2007-09-21', 500000 from dual union all
13 select date '2007-09-28', 550000 from dual union all
14 select date '2007-09-28', 100000 from dual

Dan kueri yang dapat Anda gunakan untuk membandingkan data tahun 2007 dan 2008:
SQL> select to_char(pd_end_dt,'dd-mm') day_and_month

Meskipun agak bertele-tele, saya pikir itu berbicara sendiri. Anda mungkin menyukai penulisan ulang berikut, karena tidak mengulangi fungsi agregat sebanyak dalam kueri di atas:
SQL> select day_and_month
2 , sum2007
3 , sum2008
4 , sum2008-sum2007 difference
5 , 100*(sum2008-sum2007)/sum2008 percentage_difference
6 from ( select to_char(pd_end_dt,'dd-mm') day_and_month
7 , sum(case trunc(pd_end_dt,'yyyy') when date '2007-01-01' then nrx_cnt end) sum2007
8 , sum(case trunc(pd_end_dt,'yyyy') when date '2008-01-01' then nrx_cnt end) sum2008
9 from lnd_wkly_plan_rx_summary
10 where ( pd_end_dt >= date '2007-09-01'
11 and pd_end_dt < date '2007-09-30'
12 )
13 or ( pd_end_dt >= date '2008-09-07'
14 and pd_end_dt < date '2008-09-30'
15 )
16 group by to_char(pd_end_dt,'dd-mm')
