sqlserver查看锁及解锁

sqlserver查看锁及解锁

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'

 

spid   锁表进程 

tableName   被锁表名

 

解锁：

 

declare @spid  int 

Set @spid  = 71--锁表进程

declare @sql varchar(1000)

set @sql='kill '+cast(@spid  as v
