SELECT HOME_DEPT, LINECODE, SUM(TOTAL_HRS),  
       TO_CHAR ( 
       100*RATIO_TO_REPORT(SUM(TOTAL_HRS))
       OVER (PARTITION BY HOME_DEPT), 
       '990.00L', 'NLS_CURRENCY=%'
       ) PCT_JOB
       FROM TABLE 
       GROUP BY HOME_DEPT, LINECODE ORDER BY HOME_DEPT ASC, PCT_JOB DESC;

The above Oracle query works and produces results as such:

DEPT1 LINECODE1 100 50% 
DEPT1 LINECODE2  50 25%
DEPT1 LINECODE3  50 25%

DEPT2 LINECODE1  20 12.5% 
DEPT2 LINECODE2  20 12.5%
DEPT2 LINECODE3  20 12.5%
DEPT2 LINECODE4  20 12.5%
DEPT2 LINECODE5  20 12.5%
DEPT2 LINECODE6  20 12.5%
DEPT2 LINECODE7  20 12.5%
DEPT2 LINECODE8  20 12.5%

now I want to rollup per department to get results as such:

DEPT1 LINECODE1 100  50% 
DEPT1 LINECODE2  50  25%
DEPT1 LINECODE3  50  25%
DEPT1           200 100%  <--- desired

DEPT2 LINECODE1  20  12.5% 
DEPT2 LINECODE2  20  12.5%
DEPT2 LINECODE3  20  12.5%
DEPT2 LINECODE4  20  12.5%
DEPT2 LINECODE5  20  12.5%
DEPT2 LINECODE6  20  12.5%
DEPT2 LINECODE7  20  12.5%
DEPT2 LINECODE8  20  12.5%
DEPT2           160 100.0%    <--- desired

I have tried various things such as GROUPING SETS but then my PCT_JOB values are wrong.

GROUPING这里记录了一个函数。此函数将告诉您给定行是否为“超级聚合”行。然后，您可以根据该行的值进行排序。

请注意，我对 PCT_JOB 列的定义有点杂乱无章，因为我将普通行和“超级聚合”行分别分组。

下面的 SQL 查询应该可以满足您的需求。

select
  home_dept,
  linecode,
  total_hrs,
  to_char(
    100 * ratio_to_report(total_hrs) over (partition by home_dept, linecode_group),
    '990.00L', 'NLS_CURRENCY=%') as pct_job 
from (
  SELECT 
    HOME_DEPT, 
    LINECODE, 
    SUM(TOTAL_HRS) as total_hrs, 
    grouping(linecode) as linecode_group
  FROM my_TABLE 
  GROUP BY grouping sets ((home_dept), (HOME_DEPT, LINECODE))
)
ORDER BY HOME_DEPT ASC, linecode_group, pct_job desc

另外，我在这里使用了分组集，但可以只使用：

  GROUP BY home_dept, rollup(LINECODE)

有一个SQLFiddle 可以让你看到一个例子。

这是一个不需要外部查询的答案。它基于 Mike Meyers 的回答，但现在行代码的 GROUPING 在 PARTITION BY 子句和 ORDER BY 子句中指定：

SELECT
    home_dept,
    linecode,
    SUM(total_hrs) AS total_hrs, 
    TO_CHAR(100 * RATIO_TO_REPORT (SUM(total_hrs))
            OVER (PARTITION BY home_dept, GROUPING(linecode)),
            '990.00L', 'NLS_CURRENCY=%') AS pct_job
FROM my_table
GROUP BY GROUPING SETS ((home_dept), (home_dept, linecode))
ORDER BY home_dept, GROUPING(linecode), pct_job DESC

上面的代码使用 GROUP BY GROUPING SETS 但下面的 GROUP BY 也可以工作：

GROUP BY home_dept, ROLLUP(linecode)

也仅供参考：最初的问题希望线路代码按百分比降序排序，而不是按线路代码值（即线路代码名称）......但在给定的示例中，“按百分比降序”的结果看起来与“升序”相同按名字。” 如果有人想按名称升序查看线路代码，而不考虑百分比，您可以将 ORDER BY 行更改为：

ORDER BY home_dept, linecode
