--锁表查询的代码有以下的形式：
select count(*) from v$locked_object;
select * from v$locked_object;
--查看哪个表被锁
Sql代码
select b.owner,b.object_name,a.session_id,a.locked_mode
from v$locked_object a,dba_objects b
where b.object_id = a.object_id;
--查看是哪个session引起的
Sql代码
select b.username,b.sid,b.serial#,logon_time
from v$locked_object a,v$session b
where a.session_id = b.sid order by b.logon_time;
执行命令：alter system kill session'1025,41';
其中1025为sid, 41为serial#.
select*from v$locked_object lo,dba_objects ao,v$session s where
ao.object_id = lo.object_id and lo.session_id=s.sid;
alter system KILL session '208,393';
