sqlserver查看哪个表被锁表了以及解锁方法

查看sqlserver被锁的表：
select request_session_id spid,OBJECT_NAME(resource_associated_entity_id) tableName
from sys.dm_tran_locks where resource_type='OBJECT'

解锁：@spid为锁表进程
declare @spid int
Set @spid = 66
declare @sql varchar(1000)
set @sql='kill '+cast(@spid as varchar)
exec(@sql)

---------查看数据库是否堵塞-----------
select * from sys.sysprocesses where blocked<>0

---------根据id查找对应的sql进程-------
dbcc inputbuffer(110)

sqlserver数据库查看死锁和阻塞语句exec sp_who_lock
