SqlServer表锁住后...

SqlServer表锁住后，必须手动杀掉死锁的会话ID，才能恢复正常，相关操作：

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%’);
