Oracle Sql. Запрос сводится, но основной столбец отображается только один раз.

Question

ПРЕДЫДУЩИЕ ДАННЫЕ, КОТОРЫЕ Я ИСПОЛЬЗУЛчтобы достичь этого в sql?

Ниже должна быть любая идея о том, как этого добиться.

  TOWNSHIP             PCT      TOTAL
  -------------------- --- ----------
  Agat                 4          688
                       04A        611
                       04B        603
  Total                           1902

  MY QUERY:

 COL VILLAGE FOR A20
 SET PAGESIZE 50000
  set lines 154
  --grouping(district), grouping(pct)
 select NVL(DISTRICT,'')
 district, pct,
 sum(VOTERS) as TOTAL FROM 
 (SELECT distinct DISTRICT,
 PCT,
 COUNT(*) AS VOTERS
   FROM
  REG_TAB
 JOIN PCT_LOOKUP
 ON
 PCT=PERCINCT_MAP
 AND VILLAGE IN (UPPER(SUBSTR(DISTRICT,1,INSTR(DISTRICT,'/',1)-1)),UPPER( 
 SUBSTR(REPLACE(DISTRICT,'.',''),INSTR(DISTRICT,'/',1)+1,99))) GROUP BY   
 PCT,DISTRICT ORDER BY to_number(substr(PCT,1,length(PCT)- 
 nvl(length(replace(translate(PCT,'0123456789','0000000000'),'0','')),0))),
 substr(PCT,1+length(PCT)- 
 nvl(length(replace(translate(PCT,'0123456789','0000000000'),'0','')),0)) 
 NULLS FIRST) group by ROLLUP(district, pct) ;

Я хочу получить, как в приведенной выше таблице, я пробовал сворачивать, но это приносит имя столбца, ноЯ не хочу, чтобы имя этого столбца отображалось несколько раз, вместо этого достаточно одного раза.

Просто выясняю, как этого добиться.

Answer 1

Функции ROLLUP, CUBE, GROUPING и наборы GROUPING и функция ROW_NUMBER ()?
