我试图查询：

WITH cte AS 
(
    SELECT 
     Terminal_Id, Close_date, Close_time, SlNo, 
     ROW_NUMBER() OVER (ORDER BY Close_date,Close_time) AS RN 
    FROM 
     tablename

UPDATE cte 
SET SlNo = RN 

Answer 1

SELECT SlNo,ROW_NUMBER() OVER (ORDER BY Close_date,Close_time) AS RN 
FROM tablename 
) 
UPDATE cte SET SlNo=RN
