job                   department
-------------------------------------------
manager              accounting
president            accounting
manager              accounting
clerk                accounting

我需要提取如下数据

status       status_numbers        status2           status_numbers2            outstanding                     total
-----------------------------------------------------------------------------------------------------------------
manager             5              manager               14                 total-status_numbers2               14
president           1              president             9                  total-status_numbers2               14 
clerk               3              clerk                 8                  total-status_numbers2               14
analyst             2              analyst               5                  total-status_numbers2               14
security            3              security              3                  total-status_numbers2               14

在 status_numbers2 列中，我们需要按以下方式提取数据 对于经理 o 来自progress_cmc_status_numbers 字段的经理、总裁、文员、分析师、安全人员的总和(14)

总统 来自progress_cmc_status_numbers 字段的总裁、文员、分析师、安全人员的总和(9)

为文员 progress_cmc_status_numbers 字段中的文员、分析师、安全人员的总和(8)

对于分析师 分析师总和，来自 progress_cmc_status_numbers 字段的安全性 (5)

为了安全 progress_cmc_status_numbers 字段的安全总和(3)

Answer 1

试试这样的：

select status ,status_numbers, SUM(status_numbers) OVER (ORDER BY ordr desc ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) status_numbers2
from
(
select "job" status, count(*) status_numbers , decode("job", 'manager', 1, 'president',2, 'clerk', 3,'analyst', 4, 'security', 5) ordr
from emp
group by "job") t
