Question

有谁知道如何解决此错误？这个sql工作正常，但对于'cumulinvoiced'分区功能。我正在尝试添加累计总数，但它似乎不适用于内联视图。

SELECT a.mois, a.supid, a.status, COUNT (a.status), 
       SUM (COUNT (a.status) OVER (ORDER BY a.status, a.supid, a.dossier, a.mois)) cumulinvoiced 
from (SELECT TO_CHAR (impdate, 'YYYYMM') mois, 
             benefit#sup_inv_id supid,
             SUBSTR (si_benstatus, 1, 1) status,
             files#fil_secid dossier
        FROM sbbenefit   
       WHERE benefit#sup_inv_id = 30515   
         AND SUBSTR(si_benstatus, 1, 1) = '2'
    GROUP BY TO_CHAR (impdate, 'YYYYMM'), benefit#sup_inv_id ,SUBSTR (si_benstatus, 1, 1), files#fil_secid) a 
GROUP BY a.mois, a.supid, a.status 
order BY a.supid, a.mois , a.status

Answer 1

汇总COUNT应该是分析SUM的参数，反之亦然：

SELECT a.mois, a.supid, a.status, COUNT (a.status), 
       SUM (COUNT (a.status)) OVER (ORDER BY a.status, a.supid, a.dossier, a.mois) cumulinvoiced 
from (SELECT TO_CHAR (impdate, 'YYYYMM') mois, 
             benefit#sup_inv_id supid,
             SUBSTR (si_benstatus, 1, 1) status,
             files#fil_secid dossier
        FROM sbbenefit   
       WHERE benefit#sup_inv_id = 30515   
         AND SUBSTR(si_benstatus, 1, 1) = '2'
    GROUP BY TO_CHAR (impdate, 'YYYYMM'), benefit#sup_inv_id ,SUBSTR (si_benstatus, 1, 1), files#fil_secid) a 
GROUP BY a.mois, a.supid, a.status 
order BY a.supid, a.mois , a.status

Answer 2

分析和分组不一定能够协同工作。如果您首先执行分组，然后对该结果执行分析查询，我认为它应该有效：

SELECT mois, supid, status, status_count,
      SUM (status_count OVER (ORDER BY a.status, a.supid, a.dossier, a.mois)) cumulinvoiced 
from
(SELECT  a.mois, a.supid, a.status, COUNT (a.status) status_count
from 
(
SELECT  
 TO_CHAR (impdate, 'YYYYMM') mois, 
 benefit#sup_inv_id supid,
 SUBSTR (si_benstatus, 1, 1) status,
 files#fil_secid dossier
FROM sbbenefit   
WHERE  benefit#sup_inv_id = 30515   
 AND  SUBSTR (si_benstatus, 1, 1) = '2'
GROUP BY 
 TO_CHAR (impdate, 'YYYYMM'), 
 benefit#sup_inv_id ,
 SUBSTR (si_benstatus, 1, 1),
 files#fil_secid  
) a 
GROUP BY 
a.mois, a.supid, a.status
) 
order BY 
supid, mois , status

ORA-30483：这里不允许使用窗口函数
