sql-server - 如何在 Sql Server 2005 上获取上次插入/更新/删除日期时间？

Question

不是 my previous question 的副本

当表/数据库在 Sql Server 2005 上插入/更新/删除时，有什么方法可以获得最新的日期时间吗？最好不要创建触发器..

我知道当您需要每行的最后一次更新时，您需要触发器。但是我不确定当您只想获取整个表的最后更新时是否需要它们。

您可以轻松获取上次插入/更新/删除的日期，如下所示:

CREATE FUNCTIOn fn_TablesLastUpdateDate(@Date NVARCHAR(20))

RETURNS @table TABLE(TableName NVARCHAR(40), LastUpdated Datetime)

AS

BEGIN


IF(@Date='') OR (@Date Is Null) OR (@Date='0')

    BEGIN
        INSERT INTO @table
        SELECT TOP 100 PERCENT TABLENAME,LASTUPDATED FROM 
        (
            SELECT  B.NAME AS 'TABLENAME', MAX(STATS_DATE (ID,INDID)) AS LASTUPDATED
            FROM    SYS.SYSINDEXES AS A
                    INNER JOIN SYS.OBJECTS AS B ON A.ID = B.OBJECT_ID
            WHERE   B.TYPE = 'U'  AND STATS_DATE (ID,INDID) IS NOT NULL 
            GROUP BY B.NAME
        ) AS A
        ORDER BY LASTUPDATED DESC
    END
ELSE

    BEGIN
        INSERT INTO @table
        SELECT TOP 100 PERCENT TABLENAME,LASTUPDATED FROM 
        (
            SELECT  B.NAME AS 'TABLENAME', MAX(STATS_DATE (ID,INDID)) AS LASTUPDATED,
                    CONVERT(VARCHAR, MAX(STATS_DATE (ID,INDID)), 103) as Date
            FROM    SYS.SYSINDEXES AS A
                    INNER JOIN SYS.OBJECTS AS B ON A.ID = B.OBJECT_ID
            WHERE   B.TYPE = 'U'  AND STATS_DATE (ID,INDID) IS NOT NULL 
            GROUP BY B.NAME
        ) AS A
        WHERE Date=@Date
        ORDER BY LASTUPDATED DESC
    END
RETURN

END



-- SELECT * from fn_TablesLastUpdateDate('06/11/2012')
