Oracle SQL PERCENT_RANK在多个分组中汇总数据

Question

我试图根据不同的分组显示百分等级..我最初尝试的代码类似于下面的代码。

我没有意识到的问题是'over partition'不会忽略我拥有的分组。由于我无法找到解决方法...我最终使用CTE将数据分组到我想要的百分比排名中，然后对每个需要的百分位组使用子查询（10+）。

是否有更有效的方法来做我想要的东西？

SELECT 
,employee 
,dept 
,location 
,shift 
,fq 
,fm 
,day 
,sum(calls) 
,sum(handletime) 

/*YTD P RANKS */ 

,PERCENT_RANK() over (partition by dept order by DECODE(sum(calls),0,0,sum(handletime)/sum(calls)) DESC) as YTD_P_RANK_ALL_LOCATIONS 
,PERCENT_RANK() over (partition by dept, location by DECODE(sum(calls),0,0,sum(handletime)/sum(calls)) DESC) as YTD_P_RANK_LOCAL_LOCATION 
,PERCENT_RANK() over (partition by dept, shift by DECODE(sum(calls),0,0,sum(handletime)/sum(calls)) DESC) as YTD_P_RANK_SHIFT 

/*QTD P RANKS */ 

,PERCENT_RANK() over (partition by fq, dept order by DECODE(sum(calls),0,0,sum(handletime)/sum(calls)) DESC) as QTD_P_RANK_ALL_LOCATIONS 
,PERCENT_RANK() over (partition by fq, dept, location by DECODE(sum(calls),0,0,sum(handletime)/sum(calls)) DESC) as QTD_P_RANK_LOCAL_LOCATION 
,PERCENT_RANK() over (partition by fq, dept, shift by DECODE(sum(calls),0,0,sum(handletime)/sum(calls)) DESC) as QTD_P_RANK_SHIFT 


from table1 

group by 

,employee 
,dept 
,location 
,shift 
,fq 
,fm 
,day 

Answer 1

（编辑）我想你可能会得到这个工作，如果你在3个步骤分割你的查询：

1. 首先计算的款项。
2. 计算百分比排名。
3. 应用您的最终group by。

希望这能让你更接近你想要做的事。
