匯總/遞歸添加SQL Server 2008

Question

我有一個with rollup查詢with rollup其輸出類似的數據（查詢有點忙，但是可以在需要時發布）

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

如何保持連續的總計percent ？ 假設我需要找到最低的15個百分位數，在這種情況下為3+13=16所以我想返回最后一行

range    subCounts    counts    percent
10-19    13           100       13.0

EDIT1：這里查詢

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，所以對於任何可能將其用作參考的人，我都想出了我需要做的事情。

我將row_number() over(bin) as rownum到查詢中，並將所有這些保存為視圖。

然后我用

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

通過加入t1.rownum> = t2.rownum，您可以獲得滾動計數之類的東西。

這並不是我一直在尋找的東西，但它在相同的軌道上： http : //blog.tallan.com/2011/12/08/sql-server-2012-windowing-functions-part-1-of- 2-running-and-sliding-aggregates /和http://blog.tallan.com/2011/12/19/sql-server-2012-windowing-functions-part-2-of-2-new-analytic-functions / -簽出PERCENT_RANK CUME_DIST PERCENTILE_CONT PERCENTILE_DISC
