我需要找到整个表的max(n.LastEdited)(最新编辑日期)并将其写在每一行上。

我有的:

SELECT n.ID,
n.Title,
n.News,
(SELECT max(n.LastEdited)) AS NewsLastEdited
FROM News AS n
ORDER BY n.ID DESC
LIMIT 0,20


我得到了什么(不显示ID,标题,新闻等):

NewsLastEdited
2012-10-25 10:54:24
2012-10-25 10:54:12
2012-10-25 10:54:02


我想要的是:

NewsLastEdited
2012-10-25 10:54:24
2012-10-25 10:54:24
2012-10-25 10:54:24

最佳答案

SELECT  n.*
FROM    news n
        INNER JOIN
        (
            SELECT  ID, Max(LastEdited) lastEdit
            FROM news
            GROUP BY ID
        ) x ON n.ID = x.ID AND
               n.LastEdited = x.LastEdit
-- WHERE ...
-- ORDER BY ...
-- LIMIT ...
