  • Sql Server 2008 【存储过程】 死锁 查询和杀死

    1 . 使用数据库中,可能出现死锁, 导致程序 无法正常使用.

    Create procedure [dbo].[sp_who_lock]
    (
    @bKillPID Bit=0 -- 0: 查询 1: 结束掉相对应的死锁ID (可能导致数据异常)
    )
    as
    begin
    declare @spid int
    declare @blk int
    declare @count int
    declare @index int
    declare @lock tinyint
    set @lock=0
    create table #temp_who_lock
    (
    id int identity(1,1),
    spid int,
    blk int
    )
    if @@error<>0 return @@error
    insert into #temp_who_lock(spid,blk)
    select 0 ,blocked
    from (select * from master..sysprocesses where blocked>0)a
    where not exists(select * from master..sysprocesses where a.blocked =spid and blocked>0)
    union select spid,blocked from master..sysprocesses where blocked>0
    if @@error<>0 return @@error
    select @count=count(*),@index=1 from #temp_who_lock
    if @@error<>0 return @@error
    if @count=0
    begin
    select '没有阻塞和死锁信息'
    return 0
    end
    Declare @SBak Varchar(10)
    while @index<=@count
    begin
    if exists(select 1 from #temp_who_lock a where id>@index and exists(select 1 from #temp_who_lock where id<=@index and a.blk=spid))
    begin
    set @lock=1
    select @spid=spid,@blk=blk from #temp_who_lock where id=@index
    select '引起数据库死锁的是: '+ CAST(@spid AS VARCHAR(10)) + '进程号,其执行的SQL语法如下'
    select @spid, @blk
    dbcc inputbuffer(@spid)
    dbcc inputbuffer(@blk)
    If @bKillPID =1
    Begin
