由于缺少表格结构等，这里有一些“虚拟”代码。我们的想法是首先评估每个客户的最小和最大日期，然后在相应的记录之间进行连接：

WITH cte AS(
  SELECT [Customer Code_Transaction]) AS CustomerCode
        ,min([Invoice Date_Transaction]) AS MinDate
        ,max([Invoice Date_Transaction]) AS MaxDate
    FROM [yourtable...]
    GROUP BY [Customer Code_Transaction]
)
SELECT t1.[Invoice Date_Transaction]
      ,t1.[Customer Code_Transaction]
      ,t1.[Customer Name_Transaction]
      ,t2.[Address_CustReport]
   FROM [yourtable...] AS t1
   JOIN cte AS c ON c.MinDate = t1.[Invoice Date_Transaction] AND c.CustomerCode = t1.[Customer Code_Transaction]
   JOIN [yourtable...] AS t2 ON t2.[Customer Code_Transaction] = c.[Customer Code_Transaction] AND t2.[Invoice Date_Transaction] = c.MaxDate
