是否有一种方法列出当前在MS SQL Server上运行的查询(无论是通过企业管理器还是SQL)和/或谁连接?
我想我有一个很长时间运行的查询正在我的一个数据库服务器上执行,我想跟踪它并停止它(或不断启动它的人)。

试图把事情放在一起(希望有帮助):
SELECT
p.spid,
RIGHT(CONVERT(varchar, DATEADD(ms, DATEDIFF(ms, p.last_batch, GETDATE()), '1900-01-01'), 121), 12) AS [batch_duration],
p.[program_name],
p.hostname,
MAX(p.loginame) AS loginame,
(SELECT SUBSTRING(text, COALESCE(NULLIF(spid.stmt_start, 0), 1) + 1, CASE spid.stmt_end WHEN -1 THEN DATALENGTH(text) ELSE (spid.stmt_end - spid.stmt_start) END) FROM ::fn_get_sql(spid.[sql_handle])) AS [sql]
FROM
master.dbo.sysprocesses p
LEFT JOIN (
SELECT
ROW_NUMBER() OVER(PARTITION BY spid ORDER BY ecid) AS i,
spid,
[sql_handle],
CASE stmt_start WHEN 0 THEN 0 ELSE stmt_start / 2 END AS stmt_start,
CASE stmt_end WHEN -1 THEN -1 ELSE stmt_end / 2 END AS stmt_end
FROM sys.sysprocesses
) spid ON p.spid = spid.spid AND spid.i = 1
WHERE
p.spid > 50
AND p.status NOT IN ('background', 'sleeping')
AND p.cmd NOT IN ('AWAITING COMMAND', 'MIRROR HANDLER', 'LAZY WRITER', 'CHECKPOINT SLEEP', 'RA MANAGER')
GROUP BY
p.spid,
p.last_batch,
p.[program_name],
p.hostname,
spid.stmt_start,
spid.stmt_end,
spid.[sql_handle]
ORDER BY
batch_duration DESC,
p.spid
;

这将显示在SQL 2000或SQL 2005服务器上运行时间最长的spid:
select
P.spid
, right(convert(varchar,
dateadd(ms, datediff(ms, P.last_batch, getdate()), '1900-01-01'),
121), 12) as 'batch_duration'
, P.program_name
, P.hostname
, P.loginame
from master.dbo.sysprocesses P
where P.spid > 50
and P.status not in ('background', 'sleeping')
and P.cmd not in ('AWAITING COMMAND'
,'MIRROR HANDLER'
,'LAZY WRITER'
,'CHECKPOINT SLEEP'
,'RA MANAGER')
order by batch_duration desc
如果你需要从结果中看到一个给定spid的SQL运行,可以使用这样的方法:
declare
@spid int
, @stmt_start int
, @stmt_end int
, @sql_handle binary(20)
set @spid = XXX -- Fill this in
select top 1
@sql_handle = sql_handle
, @stmt_start = case stmt_start when 0 then 0 else stmt_start / 2 end
, @stmt_end = case stmt_end when -1 then -1 else stmt_end / 2 end
from sys.sysprocesses
where spid = @spid
order by ecid
SELECT
SUBSTRING( text,
COALESCE(NULLIF(@stmt_start, 0), 1),
CASE @stmt_end
WHEN -1
THEN DATALENGTH(text)
ELSE
(@stmt_end - @stmt_start)
END
)
FROM ::fn_get_sql(@sql_handle)
下面是一个查询,它将显示任何阻塞的查询。我不完全确定它是否只会显示缓慢的查询:
SELECT p.spid
,convert(char(12), d.name) db_name
, program_name
, convert(char(12), l.name) login_name
, convert(char(12), hostname) hostname
, cmd
, p.status
, p.blocked
, login_time
, last_batch
, p.spid
FROM master..sysprocesses p
JOIN master..sysdatabases d ON p.dbid = d.dbid
JOIN master..syslogins l ON p.sid = l.sid
WHERE p.blocked = 0
AND EXISTS ( SELECT 1
FROM master..sysprocesses p2
WHERE p2.blocked = p.spid )
SELECT
p.spid, p.status, p.hostname, p.loginame, p.cpu, r.start_time, r.command,
p.program_name, text
FROM
sys.dm_exec_requests AS r,
master.dbo.sysprocesses AS p
CROSS APPLY sys.dm_exec_sql_text(p.sql_handle)
WHERE
p.status NOT IN ('sleeping', 'background')
AND r.session_id = p.spid
正确的脚本应该是这样的:
select
p.spid, p.status,p.hostname,p.loginame,p.cpu,r.start_time, t.text
from sys.dm_exec_requests as r, sys.sysprocesses p
cross apply sys.dm_exec_sql_text(p.sql_handle) t
where p.status not in ('sleeping', 'background')
and r.session_id=p.spid
