Суммируйте значения столбца с помощью подзапроса

Question

В базе данных oracle у меня есть данные, разделенные на «Центральная, Группа, ВРЕМЕННЫЙ НАБОР, ГОД, Квартал». Однако значения измерений, которые у меня были, существуют только для групп центров, что означает, что общие значения центров не зарегистрированы, и я должен их вычислить.

My idea was to use a subquery as the following:

WITH table1 as (SELECT 
DMDO_ESTRUTURA_ORGANIZA_ET_V.CENTRAL_ABR AS NOME,
CASE
  WHEN DMDO_ESTRUTURA_ORGANIZA_ET_V.CENTRAL_ABR  <> 'NA'
  THEN substr(DMDO_ESTRUTURA_ORGANIZA_ET_V.CENTRAL_ABR,-2)
ELSE 'NA'
END AS CENTRAL,

CASE
  WHEN DMDO_ESTRUTURA_ORGANIZA_ET_V.GRUPO_ABR  <> 'NA'
  THEN 'G' || substr(DMDO_ESTRUTURA_ORGANIZA_ET_V.GRUPO_ABR,-1,1)
  ELSE 'NA'
END AS GRUPO, 

TRUNC(FOMNMN001."IMN_ANO_MES" , 'MM') AS TIMESTAMP,
EXTRACT(year from FOMNMN001."IMN_ANO_MES") AS YEAR,

CASE 
 WHEN EXTRACT(month from FOMNMN001."IMN_ANO_MES") = '1' OR EXTRACT(month from FOMNMN001."IMN_ANO_MES") = '2' OR EXTRACT(month from FOMNMN001."IMN_ANO_MES") = '3' 
 THEN '1'
 WHEN EXTRACT(month from FOMNMN001."IMN_ANO_MES") = '4' OR EXTRACT(month from FOMNMN001."IMN_ANO_MES") = '5' OR EXTRACT(month from FOMNMN001."IMN_ANO_MES") = '6' 
 THEN '2'
 WHEN EXTRACT(month from FOMNMN001."IMN_ANO_MES") = '7' OR EXTRACT(month from FOMNMN001."IMN_ANO_MES") = '8' OR EXTRACT(month from FOMNMN001."IMN_ANO_MES") = '9' 
 THEN '3'
 WHEN EXTRACT(month from FOMNMN001."IMN_ANO_MES") = '10' OR EXTRACT(month from FOMNMN001."IMN_ANO_MES") = '11' OR EXTRACT(month from FOMNMN001."IMN_ANO_MES") = '12' 
 THEN '4'
 END AS QUARTER,

 SUM(  FOMNMN001."IMN_TOTAL_OC") AS IMN_TOTAL_OC ,
 SUM(  FOMNMN001."IMN_TOTAL_OCNP") AS IMN_TOTAL_OCNP ,

INNER JOIN   DMDO_TEMPO

AND   DMDO_TEMPO.DATA >= '20190101'

Кто-нибудь знает, как это сделать?

Вы можете использовать GROUP BY ROLLUP () для вычисления промежуточных итогов и общего итога - см. документацию и примеры . Предположим, у нас есть следующая ситуация (ORIGINAL - это имя таблицы или имя представления):

select
 nome, central, grupo, trunc( tstamp )
, yr, quarter, totaloc, totalocnp 
from original ;

   NOME    CENTRAL    GRUPO    TRUNC(TSTAMP)      YR    QUARTER    TOTALOC    TOTALOCNP

DBfiddle здесь .

Еще одна мелочь: глядя на ваш второй снимок экрана, мы видим, что вы используете CASE ... EXTRACT ... для нахождения «чисел четверти». Это слишком сложно. Просто используйте TO_CHAR (thedate, 'Q').

-- eg
select to_char( systimestamp, 'Q' ) from dual ;

   TO_CHAR(SYSTIMESTAMP,'Q') 
____________________________ 
3  

-- with your "original" table:
select to_char( trunc( tstamp ), 'Q' ) from original ;
