1、/*--处理死锁
查看当前进程,或死锁进程,并能自动杀掉死进程
因为是针对死的,所以如果有死锁进程,只能查看死锁进程
当然,你可以通过参数控制,不管有没有死锁,都只查看死锁进程
--邹建 2004.4--*/
/*--调用示例
exec p_lockinfo
--*/
create proc p_lockinfo
@kill_lock_spid bit=1, --是否杀掉死锁的进程,1 杀掉,0 仅显示
@show_spid_if_nolock bit=1 --如果没有死锁的进程,是否显示正常进程信息,1 显示,0 不显示
as
declare @count int,@s nvarchar(1000),@i int
select id=identity(int,1,1),标志,

2、稍加改造就能变成自动杀进程的过程 CREATE PROCEDURE auto_checkblocks AS set nocount on if exists ( select * from master..sysprocesses where blocked <> 0 ) begin /* show top blockers, but no duplicates */ select convert(char(24),getdate(),13) select '注意发生阻塞！请不要慌张，请仔细查看下面的信息。导致问题的锁进程：' select '请尝试使用KILL [SPID] 来杀进程' select '请尝试使用SP_LOCK [SPID]来显示锁信息，用OBJECT_NAME(ID)来显示锁对象名称或用sp_who [SPID] 来显示信息' select '在使用OBJECT_NAME显示对象名称时请注意对应的db_id' select distinct '进程ID' = str( spid, 4 ), '进程ID状态' = convert( char(10), status ), '分块进程的进程ID' = str( blocked, 2 ), '工作站名称' = convert( char(10), hostname ), '执行命令的用户' = convert( char(10), suser_name( uid ) ), '数据库名' = convert( char(10), db_name( dbid ) ), '应用程序名' = convert( char(10), program_name ), '正在执行的命令' = convert( char(16), cmd ), '累计cpu时间' = str( cpu, 7 ), 'IO' = str( physical_io, '登录名' = loginame from master..sysprocesses where spid in ( select blocked from master..sysprocesses ) and blocked = 0 order by str(spid,4) /* 显示阻塞牺牲品 */ select '以上阻塞的牺牲品' select '进程ID[SPID]' = str( spid, '登录名' = loginame from master..sysprocesses where blocked <> 0 order by spid end else begin select '恭喜！当前没有阻塞，当前的进程信息如下.', convert (char(24),13) select '进程ID' = str( spid, '登录名' = loginame from master..sysprocesses where blocked = 0 order by spid end return GO
