Question

因此，我尝试合并具有几乎相同结构但不同where子句的代码。我现在唯一能做的就是结合他们。

这是我的代码片段：

insert into #tempAging
    select 
        mm0.transid, max(mm0.mi) as Mi,  
        CASE 
            when (max(mm0.DueDate) > @StatementDate) 
               then 
                  case  
                     when sum(isnull(mm0.OverDueAmt, 0)) = 0 
                        then '01 CURRENT AND NEW ACCOUNTS'
                     when ((((sum(isnull(mm0.OverDueAmt, 0)))  / (max(mm0.MI))) > 0) AND ((((sum(isnull(mm0.OverDueAmt, 0))) / (max(mm0.MI))) <= 1) )) 
                        then '02 ONE(1) MONTH'
                     when ((((sum(isnull(mm0.OverDueAmt,0)))/(max(mm0.MI))) > 1 ) AND ((((sum(isnull(mm0.OverDueAmt,0)))/(max(mm0.MI))) <=2) )) 
                        then '03 TWO(2) MONTHS'

我希望有人可以帮助我。 TIA！

Answer 1

根据我的理解，你基本上需要的是将两个逻辑表达式合二为一，避免结合。

where isnull(e0.transcode,'') not in (N'BEG',N'ADJ') and e3.Segment_0 = N'11210'

OR

where isnull(e0.transcode,'') in (N'BEG',N'ADJ') and e3.Segment_0 = N'11210' and e0.TransType = N'30'

基本上是一个，

(A and B and C) or ((not A) and B)

由于这已经是最简单的see here形式，您可以使用

where (isnull(e0.transcode,'') not in (N'BEG',N'ADJ') and e3.Segment_0 = N'11210') or (isnull(e0.transcode,'') in (N'BEG',N'ADJ') and e3.Segment_0 = N'11210' and e0.TransType = N'30')

在第一个选择并删除联盟的第二部分。

因此，您的最终查询将如下所示：

insert into #tempAging

CASE when ( max(mm0.DueDate) > @StatementDate) then

when ((((sum(isnull(mm0.OverDueAmt,0)))/(max(mm0.MI))) > 1 ) AND ((((sum(isnull(mm0.OverDueAmt,0)))/(max(mm0.MI))) <=2) )) then '03 TWO(2) MONTHS'
when ((((sum(isnull(mm0.OverDueAmt,0)))/(max(mm0.MI))) > 2 ) AND ((((sum(isnull(mm0.OverDueAmt,0)))/(max(mm0.MI))) <=3) )) then '04 THREE(3) MONTHS'
when ((((sum(isnull(mm0.OverDueAmt,0)))/(max(mm0.MI))) > 3 ) AND ((((sum(isnull(mm0.OverDueAmt,0)))/(max(mm0.MI))) <=4) )) then '05 FOUR(4) MONTHS'
