Oracle SQL - 使用分析函數對聚合函數進行分組？

Question

我有這樣的SQL：

SELECT 
    TO_CHAR(dateinvoiced, 'YYYY') AS year, 
    TO_CHAR(dateinvoiced, 'MM') AS month,  
    name, 
    SUM(reste) OVER (PARTITION BY name, ad_org_id) AS tot_reste_client, 
    nameregion AS region 
FROM 
    table 
GROUP BY 
    TO_CHAR(dateinvoiced, 'YYYY'), 
    TO_CHAR(dateinvoiced, 'MM'),  
    name, 
    nameregion 
ORDER BY name; 

我得到試圖把它在GROUP BY子句中，我也得到錯誤像這樣「是不是分組功能」，使用具有和它告訴我，「窗函數試圖這裏不允許「。

找不到解決辦法？我使用的Oracle 12

解析函數計算後 GROUP BY/HAVING，所以通常你可以添加聚集，reste：

SELECT 
    TO_CHAR(dateinvoiced, 'YYYY') AS year, 
    TO_CHAR(dateinvoiced, 'MM') AS month,  
    name, 
    SUM(SUM(reste)) OVER (PARTITION BY name, ad_org_id) AS tot_reste_client, 
    nameregion AS region 
FROM 
    table 
GROUP BY 
    TO_CHAR(dateinvoiced, 'YYYY'), 
    TO_CHAR(dateinvoiced, 'MM'),  
    name, 
    nameregion 
ORDER BY name; 

但是這也應該由於ad_org_id而失敗，這不在GROUP BY中，也許你可以使用MIN(ad_org_id)。
