Question

通过使用SQL服务器，我试图过滤掉与每个策略号相关联的行，当“本地货币的高级”总和为零，然后最后一行在“当前状态”中具有“取消”柱。

 Workno#            MasterPolicyNumber  EffectiveDate  CurrentStatus    PremiumLocalCurrency 
16-05-01-035210-01  42-PRP-302562-01    2016-05-12          Bound        61438
16-05-01-035210-02  42-PRP-302562-01    2016-05-12        Cancellation  -61438

以下是我使用的SQL查询

    select 
               [Workno#],
               [MasterPolicyNumber],
               [EffectiveDate],
               [CurrentStatus],
               [PremiumLocalCurrency]
              from IT.dbo.View_Rater_Of_Record
        where [MasterPolicyNumber] = '42-PRP-302562-01'  
                order 
        by [Workno#]

但是我希望通过过滤掉两行来将结果作为零记录，因为总和加起来为零，最后一行将“取消”作为状态。提前致谢。

我也尝试过使用Having子句，但是我没有得到结果。下面的行过滤第二行，因为它小于1.

 Having SUM(CAST([Premium in Local Currency]as float))>1

Answer 1

假设SQL服务器：

with Canc as
(
select MasterPolicyNumber, EffectiveDate, CurrentStatus, PremiumLocalCurrency,
       row_number() over(partition by MasterPolicyNumber order by Workno# desc) as Row_ord
from View_Rater_Of_Record
)
select C1.MasterPolicyNumber, sum(C2.PremiumLocalCurrency) as TotPLC
from Canc C1
inner join Canc C2
  on C1.MasterPolicyNumber = C2.MasterPolicyNumber
where C1.Row_Ord = 1
and C1.CurrentStatus = 'Cancellation'
group by C1.MasterPolicyNumber
having sum(C2.PremiumLocalCurrency) <> 0
