Sql server 2008 SQL Server:查询系统进程和InputBuffer

我正在尝试提取输入缓冲区数据DBCCINPUTBUFFER@SPID对于查询sysprocesss表时为数据库返回的每个记录。我很想知道是否有更好的方法来实现这一点，但也希望能纠正我目前为学习目的所做的工作

DECLARE @Max [int]
DECLARE @Min [int] = 1

SELECT @Max = COUNT(SPID)
FROM MASTER.DBO.SYSPROCESSES
WHERE DB_NAME(DBID) = 'Northwinds' AND DBID != 0

CREATE TABLE #Results (
    EventType [nvarchar](1024),
    Parameters [int],
    EventInfo [nvarchar](1024),
    SPID [int],
    STATUS [nvarchar](255),
    PROGRAM_NAME [nvarchar](1024),
    CMD [nvarchar](255),
    LOGINAME [nvarchar](255)
)

WHILE @Min <= @Max
BEGIN

    DECLARE @SPID [int]

    WITH SelectedRow AS (
        SELECT SPID, ROW_NUMBER() OVER (ORDER BY SPID) AS RowNumber
        FROM MASTER.DBO.SYSPROCESSES
        WHERE DB_NAME(DBID) = 'Northwinds' AND DBID != 0
    )

    SELECT @SPID = SPID
    FROM SelectedRow
    WHERE RowNumber = @Min

    DECLARE @InputBuffer TABLE (
        EventType [nvarchar](1024),
        Parameter [int],
        EventInfo [nvarchar](1024)
    )

    DECLARE @SysProcesses TABLE (
        SPID [int],
        STATUS [nvarchar](255),
        PROGRAM_NAME [nvarchar](1024),
        CMD [nvarchar](255),
        LOGINAME [nvarchar](255)
    )

    INSERT @InputBuffer 
        EXEC('DBCC INPUTBUFFER('+@SPID+')')

    INSERT @SysProcesses 
        SELECT SPID, STATUS, PROGRAM_NAME, CMD, LOGINAME
        FROM MASTER.DBO.SYSPROCESSES
        WHERE DB_NAME(DBID) = 'Northwinds' AND DBID != 0 AND SPID = @SPID

    INSERT INTO #TempResults(EventType, Parameters, EventInfo, SPID, STATUS, PROGRAM_NAME, CMD, LOGINAME)
        SELECT *
        FROM @InputBuffer, @SysProcesses

    SET @Min = (@Min + 1)
END

它返回31行

但是，在执行上述循环之后，当我从TempResults中选择*时，我将返回temp表中大量的重复项…总数为10751

同样，这主要是为了学习，但也是一个非常方便的功能。我正在寻找我丢失的导致重复记录被返回的信息，以及可能更好的解决方案

您正在这样做：

INSERT #Results
SELECT * 
FROM @InputBuffer, @SysProcesses

---

这实际上是一个交叉连接，所以如果任何一个表有多行，那么结果将是COUNTleft side*COUNTright side行。也许您应该使用SELECT DISTINCT column list，或者，正如我在评论中所建议的那样，停止循环使用已弃用的系统进程并从DBCC INPUTBUFFER检索信息，即使是出于痛苦的教育目的。

请参阅下面的查询以获得更好的结果

求你了，去叫精神分裂症患者来，别再头痛了@亚伦，谢谢你，这会非常有用的。我还试图扩展我的SQL知识，所以我仍然希望得到帮助，了解循环返回这么多记录的原因。谢谢
