Oracle sql窗口函數 - 與結果總共在同一行

Question

我想使用窗口函數在同一行上顯示總計（工作人員流動率）和結果，但是我無法使其工作。它在total_labour_turnover列的over子句中爲我提供了「來自關鍵字未找到的地方」。

基本上我想要顯示總勞動力週轉量以及各行的勞動力週轉量。請注意，我不想要一個總計。

任何人都知道如何做到這一點？

     active.flexi_perm, 
     active.active_count, 
     nvl(term.term_count, 0) term_count, 
     round(nvl(term.term_count, 0)/active.active_count * 100, 2) labour_turnover, 
     round(sum(nvl(term.term_count, 0))/sum(active.active_count) * 100, 2) over (order by 1) total_labour_turnover

     ) term 
where term.cost_centre (+) = active.cost_centre 
and term.flexi_perm (+) = active.flexi_perm 

Answer 1

請嘗試以下操作，它應該幫助：

round(sum(nvl(term.term_count, 0)) over()/sum(active.active_count) over() * 100, 2) total_labour_turnover 

你在你的表達有兩個SUM函數均需要是一個解析函數。

Answer 2

據對解析函數Oracle文檔，所述order by子句自動意味着rows between unbounded preceding and current row運行窗口。

如果你不希望運行總和，而是一個整體的總和，刪除你的分析sum()功能的over子句order by 1，把一個partition by null有代替。或者用空的括號嘗試，也可能工作。
