sqlserver查看死锁进程工具脚本p_lockinfo

/* 
-- 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
-- 调用示例： 
   exec [dbo].[p_lockinfo] 0,0
*/ 
CREATE PROCEDURE [dbo].[p_lockinfo]
    @kill_lock_spid bit = 0,--是否杀掉死锁的进程,1 杀掉,0 仅显示
    @show_spid_if_nolock bit = 0 --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
