如何在下面的自动增长查询中添加日期和时间？

  • 772

在尝试防止自动增长发生时，我在这里得到了这个很好的脚本。

然而，如果确实发生了，我需要知道如何找出它。我可以使用Max Vernon 编写的这个非常好的脚本来做到这一点。

                        print @@servername + ' - ' + SUBSTRING(@@version,1,COALESCE(CHARINDEX('Copyright',@@version,0)-1,108))
                        SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED
                        SET NOCOUNT OFF


/*

    by:             Max Vernon
    date:           2014-10-01
*/
DECLARE @Version NVARCHAR(255);
DECLARE @VersionINT INT;
SET @Version = CONVERT(NVARCHAR(255),SERVERPROPERTY('ProductVersion'));
SET @VersionINT = CONVERT(INT, SUBSTRING(@Version,1 ,CHARINDEX('.',@Version)-1));
DECLARE @cmd NVARCHAR(2000);
SET @cmd = '';
IF @VersionINT >= 9
BEGIN
    SET @cmd = 
'
DECLARE @trcfilename VARCHAR(1000);

SELECT @trcfilename = path 
FROM sys.traces WITH(NOLOCK)
WHERE is_default = 1;

IF COALESCE(@trcfilename,'''') <> ''''
BEGIN
SELECT [Radhe]=
    '''''''' + @@SERVERNAME + '''''','''''' +
     DB_NAME(mf.database_id) + '''''','''''' +
     mf.name + '''''','' +
     CONVERT(VARCHAR(255), a.NumberOfGrowths) + '','' +
     CONVERT(VARCHAR(255), CAST(a.DurationOfGrowthsInSeconds AS decimal(38, 20)))
    FROM
    (
        SELECT
            tt.DatabaseID AS database_id,
            tt.FileName AS LogicalFileName,
            COUNT(*) AS NumberOfGrowths,
            SUM(tt.Duration / (1000 * 1000.0)) AS DurationOfGrowthsInSeconds
            FROM sys.fn_trace_gettable(@trcfilename, default) tt
            WHERE (EventClass IN (92, 93))
            GROUP BY
                tt.DatabaseID,
                tt.FileName
    ) a
    INNER JOIN sys.master_files mf ON
        (mf.database_id = a.database_id) AND
        (mf.name = a.LogicalFileName);
END
ELSE
BEGIN
    SELECT @@SERVERNAME, ''NO TRACE FILE'';
END
';
EXEC sp_executesql @cmd;
END
ELSE
BEGIN
    SELECT [SERVER NAME]=@@SERVERNAME, [Product Version]=SERVERPROPERTY('ProductVersion');
END

缺少的是并且我想补充的是——自动增长是什么时候发生的？

我怎样才能找到它？

    根据SqlWorldWide的善意评论，

    我按照他说的做了：

    您可以从 sys.fn_trace_gettable 添加 starttime 列。请参阅Rajendra Gupta 在此处提供的示例。– SqlWorldWide

    现在我得到了自动增长发生的日期 - 包括星期几。
