SQL死锁操作 - 爱码网

这两天数据库经常被锁，所以记录一下操作：

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

--查询出死锁的SPID
select blocked
from (select * from sysprocesses where  blocked>0 ) a 
where not exists(select * from (select * from sysprocesses where  blocked>0 ) b 
where a.blocked=spid)

--输出引起死锁的操作
DBCC INPUTBUFFER (@spid)
--查询当前进程数

select count(-1) from sysprocesses 
where dbid in (select dbid from sysdatabases where name like \'%telcount%\');
