SQLServer deadlock Table View and Kill the process deadlock

1, the query deadlock table

check sentence

select    
    request_session_id spid,   
    OBJECT_NAME(resource_associated_entity_id) tableName    
from    
    sys.dm_tran_locks   
where    
    resource_type='OBJECT'

Query results are as follows

2, killing a lock

To kill a lock need to use kill spid
statement follows

kill 56
go
kill 54

3, you can create a stored procedure to view the process deadlock

code show as below

CREATE  PROCEDURE [dbo].[sp_who_lock]
AS
    BEGIN

        DECLARE @spid INT ,
            @bl INT ,
            @intTransactionCountOnEntry INT ,
            @intRowcount INT ,
            @intCountProperties INT ,
            @intCounter INT,
            @sql_handle VARBINARY(64)

        DECLARE @tmp_lock_who TABLE 
            (
              id INT IDENTITY(1, 1) ,
              spid SMALLINT ,
              bl SMALLINT,
              sql_handle VARBINARY(64)
            )
 
        IF @@ERROR <> 0
            RETURN @@ERROR
        ;
        WITH tb_blocked AS(
            SELECT spid, blocked, sql_handle FROM master..sysprocesses WHERE blocked > 0
        )
        INSERT  INTO @tmp_lock_who
                ( spid ,
                  bl, sql_handle
                )
        SELECT DISTINCT  blocked,0, p_bl.sql_handle
        FROM    tb_blocked
            CROSS APPLY (SELECT p_bl.sql_handle FROM master..sysprocesses p_bl WHERE p_bl.spid = tb_blocked.blocked) p_bl
        WHERE   NOT EXISTS ( SELECT *
                                FROM   tb_blocked a
                                WHERE  tb_blocked.blocked = a.spid )
        UNION ALL
        SELECT spid, blocked, sql_handle FROM tb_blocked

        IF @@ERROR <> 0
            RETURN @@ERROR
 
		-- 找到临时表的记录数
        SELECT  @intCountProperties = COUNT(*),
                @intCounter = 1
        FROM    @tmp_lock_who
 
        IF @@ERROR <> 0
            RETURN @@ERROR
 
        IF @intCountProperties = 0
            SELECT  '现在没有阻塞和死锁信息' AS message
		-- 循环开始
        WHILE @intCounter <= @intCountProperties
            BEGIN
				-- 取第一条记录
                SELECT  @spid = spid, @bl = bl,    @sql_handle = sql_handle
                FROM    @tmp_lock_who
                WHERE   id = @intCounter
                BEGIN
                    IF @bl = 0
                    BEGIN
                        SELECT '阻塞根源' + CAST(@spid AS VARCHAR(10)) AS [description], text AS [sql_text] FROM sys.dm_exec_sql_text(@sql_handle) AS dest
                    END
                    ELSE
                    BEGIN
                        SELECT CAST(@spid AS VARCHAR(10)) + '被' + CAST(@bl AS VARCHAR(10)) + '阻塞' AS [description], text AS [sql_text] FROM sys.dm_exec_sql_text(@sql_handle) AS dest
                    END
                    DBCC INPUTBUFFER(@spid)
                END
				-- 循环指针下移
                SET @intCounter = @intCounter + 1
            END

        RETURN 0
    END
GO

You can view the current deadlock process through the implementation of storage lock scales sp_who_lock

exec sp_who_lock

4, may be caused by wear member to kill the process deadlock stored procedure

code show as below

create proc dbo.p_killspid 
	@dbname varchar(200)    --要关闭进程的数据库名 
as  
    declare @sql  nvarchar(500)  
    declare @spid nvarchar(20)
    declare #tb cursor for 
        select spid=cast(spid as varchar(20)) from master.dbo.sysprocesses where dbid=db_id(@dbname) 
    open #tb 
    fetch next from #tb into @spid 
    while @@fetch_status=0 
    begin  
        exec('kill '+@spid) 
        fetch next from #tb into @spid 
    end  
    close #tb 
    deallocate #tb
go

Call a stored procedure exec dbo.p_killspid spid kill the process.
