查锁表和解锁表

查看被锁表

SELECT
    request_session_id spid,
    OBJECT_NAME( resource_associated_entity_id ) tableName 
FROM
    sys.dm_tran_locks 
WHERE
    resource_type = 'OBJECT'

解锁

declare @spid  int 
Set @spid  = 57 --锁表进程
declare @sql varchar(1000)
set @sql='kill '+cast(@spid  as varchar)
exec(@sql)
