sql-server – 更新表sql server中的前1条记录[重复]

参见英文答案 > How to update and order by using ms sql5个答案我的查询

UPDATE TOP (1) TX_Master_PCBA  
SET TIMESTAMP2 = '2013-12-12 15:40:31.593'
WHERE SERIAL_NO IN ('0500030309') 
ORDER BY TIMESTAMP2 DESC

使用TX_Master_PCBA表中的serial_No列我有10条记录，但我想将最新的TIMESTAMP2更新为当前日期时间。

上面的查询抛出错误：

Incorrect Syntax near the keyword ‘TOP’.

解决方法

WITH UpdateList_view AS (
  SELECT TOP 1  * from TX_Master_PCBA 
  WHERE SERIAL_NO IN ('0500030309') 
  ORDER BY TIMESTAMP2 DESC 
)

update UpdateList_view 
set TIMESTAMP2 = '2013-12-12 15:40:31.593'
