Oracle sql窗口函数 - 与结果总共在同一行

Question

我想使用窗口函数在同一行上显示总计（工作人员流动率）和结果，但是我无法使其工作。它在total_labour_turnover列的over子句中为我提供了“来自关键字未找到的地方”。

基本上我想要显示总劳动力周转量以及各行的劳动力周转量。请注意，我不想要一个总计。

任何人都知道如何做到这一点？

     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

请尝试以下操作，它应该帮助：

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

你在你的表达有两个SUM函数均需要是一个解析函数。

Answer 2

据对解析函数Oracle文档，所述order by子句自动意味着rows between unbounded preceding and current row运行窗口。

如果你不希望运行总和，而是一个整体的总和，删除你的分析sum()功能的over子句order by 1，把一个partition by null有代替。或者用空的括号尝试，也可能工作。
