1、查询被锁住的表：
select
request_session_id spid,
OBJECT_NAME(resource_associated_entity_id) tableName
from
sys.dm_tran_locks
where
resource_type='OBJECT'
2、查询结果，spid为被锁表进程id，tableName为被锁的表名
3、解除表锁定：将spid的值改为要杀死的进程id即可
declare @spid int
Set @spid = 55 ---被锁表进程id
declare @sql varchar(1000)
set @sql='kill '+cast(@spid as varchar)
exec(@sql)
