您是否正在尋找這樣的東西？

WITH cte AS
(
  SELECT *
    FROM
  (
    SELECT t.*, ROW_NUMBER() OVER (PARTITION BY RequestNo ORDER BY LastActionDate) rnum
      FROM Table1 t
  ) q
)
SELECT c1.RequestNo, c1.usercode, 
       COALESCE(c2.LastActionDate, c1.LastActionDate) ReceivedDate,
       c1.LastActionDate, c1.ActionType, 
       DATEDIFF(day, COALESCE(c2.LastActionDate, c1.LastActionDate), c1.LastActionDate) Aging
  FROM cte c1 LEFT JOIN cte c2
    ON c1.RequestNo = c2.RequestNo
   AND c1.rnum = c2.rnum + 1
 ORDER BY RequestNo, LastActionDate

輸出：
