Question

所以我有一个查询，可以选择具有长连接和聚合的数据指标。一些结果将返回看似重复的内容，除了一列，这是一个交易号。原因是对完全相同的记录进行了单独的交易。我们不能仅仅为了保存记录而删除交易。我有以下查询：

SELECT distinct (SELECT DATEADD(DAY,-1,DATEADD(MONTH,DATEDIFF(MONTH,0,MAX(GreatestDate)) + 1, 0))
                 FROM 
                (VALUES (max(th.TransactionEffectiveDt)),(max(bp.EffectiveDt)),(max(th.TransactionDt))) AS Value(GreatestDate)) AS BookDate

        THEN '0' END 
ORDER BY PolicyNumber
        ,transactionnumber
        ,Ind
        ,BOOKDATE

结果集如下：

enter image description here

注意事务编号列是否有事务4和5？其他一切都是相同的，但交易号码。我不能只删除一条记录。因此对于这个实例，由于存在重复的记录，客户端只想看到其中一个。我尝试使用row_number（）和按功能分组，但我认为由于许多连接，它会让我失望。我需要一个只显示其中一个的select语句，因为这只是一个非常大的存储过程的一部分。我已经在使用临时表了解其他内容，所以我认为我不能因为各种原因而使用它。

Answer 1

您可以使用max()（或min() - 取决于您）这样的交易号：

    (SELECT  DATEADD(DAY,-1,DATEADD(MONTH,DATEDIFF(MONTH,0,MAX(GreatestDate)) + 1, 0))
