SQL 数据库解锁

--锁表查询的代码有以下的形式
select * from v$locked_object;
select count(*) from v$locked_object;
--查看哪个表被锁
select b.owner,b.object_name,a.session_id,a.locked_mode
from v$locked_object a,dba_objects b
where b.object_id = a.object_id;


--查看是哪个session引起的
select b.username,b.sid,b.serial#,logon_time
from v$locked_object a,v$session b
where a.session_id = b.sid order by b.logon_time;

--杀掉对应进程
--其中1025为sid,41为serial#.
alter system kill session'88,13196';
