Добавьте дополнительный столбец, чтобы вычислить процент от суммы продаж за данную неделю месяца от общей суммы продаж за месяц.Укажите имя для столбца Weekly_percent_sold.Отформатируйте значения в процентах, чтобы они выводили ровно 2 символа после запятой.

Это должно помочь вам:

-- sample data
with your_query(PRODUCT_DESCRIPTION, TOTAL_AMOUNT_SOLD, WEEK_IN_MONTH) as (
    select 'size 14:00: PRODUCT_ID=PQR', 7000, '1 week' from dual union all
    select 'size 14:00: PRODUCT_ID=PQR', 5100, '2 week' from dual union all
    select 'size 14:00: PRODUCT_ID=PQR', 7800, '3 week' from dual union all
    select 'size 14:00: PRODUCT_ID=PQR', 4900, '4 week' from dual union all
    select 'size 14:00: PRODUCT_ID=PQR', 6200, '5 week' from dual union all
    select 'size 14:00: PRODUCT_ID=XYZ', 1000, '1 week' from dual union all
    select 'size 14:00: PRODUCT_ID=XYZ', 1100, '2 week' from dual union all
    select 'size 14:00: PRODUCT_ID=XYZ',  800, '3 week' from dual union all
    select 'size 14:00: PRODUCT_ID=XYZ',  900, '4 week' from dual union all
    select 'size 14:00: PRODUCT_ID=XYZ', 1200, '5 week' from dual )
-- end of sampe data
select t.*, 
       to_char(100 * TOTAL_AMOUNT_SOLD 
               / sum(TOTAL_AMOUNT_SOLD) over (partition by PRODUCT_DESCRIPTION), '999.00') percent_1,
       to_char(100 * TOTAL_AMOUNT_SOLD 
               / sum(TOTAL_AMOUNT_SOLD) over (), '999.00') percent_2
  from your_query t

Результат:

PRODUCT_DESCRIPTION        TOTAL_AMOUNT_SOLD WEEK_IN_MONTH PERCENT_1 PERCENT_2
-------------------------- ----------------- ------------- --------- ---------
size 14:00: PRODUCT_ID=PQR              7000 1 week          22.58     19.44

size 14:00: PRODUCT_ID=XYZ              1000 1 week          20.00      2.78
size 14:00: PRODUCT_ID=XYZ              1100 2 week          22.00      3.06
size 14:00: PRODUCT_ID=XYZ               800 3 week          16.00      2.22
size 14:00: PRODUCT_ID=XYZ               900 4 week          18.00      2.50
size 14:00: PRODUCT_ID=XYZ              1200 5 week          24.00      3.33

Percent_1 показывает процент для каждого продукта в отдельности, Percent_2 для всех продуктов.В предложении with, в которое я помещаю примеры данных, вы помещаете туда свой рабочий запрос.

В вашем коде есть несколько проблем, но вы не спрашиваете об этом.

Надеюсь, это поможет:)

Редактировать: Вот моя попытка полного кода.У меня нет доступа к вашим данным, я не могу их проверить, так что это может привести к опечатке, но я надеюсь, что все в порядке.Я также использовал функцию ratio_to_report вместо деления, но это необязательно, вы можете разделить сумму на сумму.
