Question

我有以下输出：

ApplicationNumber ApplicationStatusCode CreatedOn      AppStat_Disbursed/Unc

1                 AnnuledCL             1.3.2019 8:44  Uncompleted
2                 AnnuledCL             1.3.2019 8:45  Uncompleted
3                 Paid                  1.3.2019 8:54  Disbursement
3                 Paid                  1.3.2019 8:54  Uncompleted
4                 Paid                  1.3.2019 8:59  Disbursement
4                 Paid                  1.3.2019 8:59  Uncompleted
4                 Paid                  1.3.2019 8:59  Uncompleted
5                 Paid                  1.3.2019 9:03  Uncompleted
6                 RejectedAS            1.3.2019 9:04  Uncompleted

我要达到的目的是在以下情况下删除重复的application_numbers。如果一个ApplicationNumber有多个条目（即重复的条目），则应选择“付款”状态而不是“未完成”的行并对其进行优先级排序。但是，如果该applicationNumber没有“付款”状态，则它应从“未完成”状态中移出任何一行。

这是理想的结果：

ApplicationNumber ApplicationStatusCode CreatedOn     AppStat_Disbursed/Unc
1                 AnnuledCL             1.3.2019 8:44  Uncompleted
2                 AnnuledCL             1.3.2019 8:45  Uncompleted
3                 Paid                  1.3.2019 8:54  Disbursement
4                 Paid                  1.3.2019 8:59  Disbursement
5                 Paid                  1.3.2019 9:03  Uncompleted
6                 RejectedAS            1.3.2019 9:04  Uncompleted

一种解决方法是添加由ROW_NUMBER划分的ApplicationNumber，然后由AppStat_Disbursed/Unc进行排序

SELECT ApplicationNumber
      ,ApplicationStatusCode
      ,CreatedOn
      ,[AppStat_Disbursed/Unc]
  FROM (
            SELECT *
                  ,ROW_NUMBER() OVER (PARTITION BY ApplicationNumber 
                                          ORDER BY ApplicationNumber, [AppStat_Disbursed/Unc])
                             AS rn
              FROM YOURTABLE
       ) A
 WHERE rn = 1

根据另一列的条件选择行
