This is how my data looks like now i dont want to display TOWNSHIP column more than once how to achieve this in sql?这就是我的数据现在的样子我不想多次显示 TOWNSHIP 列如何在 sql 中实现这一点？
It should like below any idea on how to achieve this.它应该喜欢下面关于如何实现这一点的任何想法。
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) ;
I want to get like above table i tried rollup but that brings the column name but i dont want that column name to be displayed multiple times instead once is enough.我想像上表一样尝试汇总，但这带来了列名，但我不希望该列名显示多次，而一次就足够了。
Just figuring out how to achieve this.只是想知道如何实现这一目标。

ROLLUP, CUBE, GROUPING Functions and GROUPING SETS and the ROW_NUMBER() function? ROLLUP、CUBE、GROUPING 函数和 GROUPING SETS以及 ROW_NUMBER() 函数？
