查询表死锁和解锁

//ORACLE查询表死锁

 select object_name,machine,s.sid,s.serial#
from v$locked_object l,dba_objects o ,v$session s
where l.object_id　=　o.object_id and l.session_id=s.sid;
2.下面的语句用来杀死一个进程：
alter system kill session '24,111'; (其中24,111分别是上面查询出的sid,serial#) 

//sqlserver判断表死锁和解锁

select   request_session_id   spid,OBJECT_NAME(resource_associated_entity_id) tableName   
    from   sys.dm_tran_locks where resource_type='OBJECT'
declare @spid  int 
    Set @spid  = 60 --锁表进程
    declare @sql varchar(1000)
    set @sql='kill '+cast(@spid  as varchar)
    exec(@sql)
