Question

我有一个查询with rollup，可以输出数据（查询有点忙，但我可以在必要时发布）

range    subCounts    Counts    percent
1-9      3            100       3.0
10-19    13           100       13.0
20-29    30           100       33.0
30-39    74           100       74.0
NULL     100          100       100.0

如何保持总计percent的总和？假设我需要找到底部的15个百分位，在这种情况下3+13=16所以我希望最后一行返回读取

range    subCounts    counts    percent
10-19    13           100       13.0

EDIT1：此处是查询

select '$'+cast(+bin*10000 + ' ' as varchar(10)) + '-' + cast(bin*10000+9999 as varchar(10)) as bins, 
    count(*) as numbers,
    (select count(distinct patient.patientid) from patient 
    inner join tblclaims on patient.patientid = tblclaims.patientid
    and patient.admissiondate = tblclaims.admissiondate
    and patient.dischargedate = tblclaims.dischargedate
    inner join tblhospitals on tblhospitals.hospitalnpi = patient.hospitalnpi
    where (tblhospitals.hospitalname = 'X') 
    ) as Totals
    , round(100*count(*)/cast((select count(distinct patient.patientid) from patient 
    inner join tblclaims on patient.patientid = tblclaims.patientid
    and patient.admissiondate = tblclaims.admissiondate
    and patient.dischargedate = tblclaims.dischargedate
    inner join tblhospitals on tblhospitals.hospitalnpi = patient.hospitalnpi
    where (tblhospitals.hospitalname = 'X')) as float),2) as binsPercent


from
(

select tblclaims.patientid, sum(claimsmedicarepaid) as TotalCosts, 
    cast(sum(claimsmedicarePaid)/10000 as int) as bin
    from tblclaims inner join patient on patient.patientid = tblclaims.patientid
    and patient.admissiondate = tblclaims.admissiondate 
    and patient.dischargedate = tblclaims.dischargedate
    inner join tblhospitals on patient.hospitalnpi = tblhospitals.hospitalnpi
    where tblhospitals.hospitalname = 'X'
    group by tblclaims.patientid
)   as t 
group by bin with rollup

Answer 1

好的，所以对于任何可能使用它作为参考的人我都知道我需要做什么。

我在查询中添加了row_number() over(bin) as rownum并将所有内容保存为视图。

然后我用了

SELECT *,
          SUM(t2.binspercent) AS SUM
FROM t t1
INNER JOIN t t2 ON t1.rownum >= t2.rownum
GROUP BY t1.rownum,
         t1.bins, t1.numbers, t1.uktotal, t1.binspercent
ORDER BY t1.rownum

通过加入t1.rownum＆gt; = t2.rownum，您可以得到滚动计数的东西。
