sqlserver查询锁住sql以及解锁的方法

SELECT
    request_session_id spid,
    OBJECT_NAME(
        resource_associated_entity_id
    ) tableName
FROM
    sys.dm_tran_locks
WHERE
    resource_type = 'OBJECT' 
ORDER BY request_session_id ASC
--spid   锁表进程 
    --tableName   被锁表名

--根据锁表进程查询相应进程互锁的SQL语句
DBCC INPUTBUFFER (249)

-- 解锁：

 DECLARE
        @spid INT
    SET @spid = 52--锁表进程
    DECLARE
        @SQL VARCHAR (1000)
    SET @SQL = 'kill ' + CAST (@spid AS VARCHAR) EXEC (@SQL)

--生成解锁SQL

SELECT
  DISTINCT  'DECLARE @spid INT SET @spid = ',request_session_id,' DECLARE @SQL VARCHAR (1000) SET @SQL = ''kill '' + CAST (@spid AS VARCHAR) EXEC (@SQL);'  as s
FROM
    sys.dm_tran_locks
WHERE
    resource_type = 'OBJECT'   --spid   锁表进程 
    --tableName   被锁表名
