本文提供了一系列Oracle SQL查询语句，用于查找被锁定的对象及其相关信息，并展示了如何通过执行特定命令来解除锁定状态。适用于数据库管理员及开发人员解决Oracle数据库中表锁定的问题。
select b.owner,b.object_name,a.session_id,a.locked_mode from v$locked_object a,dba_objects b where b.object_id = a.object_id; --查找被锁的表
select b.username,b.sid,b.serial#,logon_time from v$locked_object a,v$session b where a.session_id = b.sid order by b.logon_time;
select * from v$locked_object a,v$session b where a.session_id = b.sid order by b.logon_time;
SELECT s.sid, s.serial#, s.username, s.schemaname, s.osuser, s.process, s.machine,
s.terminal, s.logon_time, l.type
FROM v$session s, v$lock l
WHERE s.sid = l.sid
AND s.username IS NOT NULL
and s.sid='4125'
ORDER BY sid
select b.username,b.sid,b.serial#,logon_time from v$locked_object a,v$session b where a.session_id = b.sid order by b.logon_time;
select * from v$locked_object a,v$session b where a.session_id = b.sid order by b.logon_time;
SELECT s.sid, s.serial#, s.username, s.schemaname, s.osuser, s.process, s.machine,
s.terminal, s.logon_time, l.type
FROM v$session s, v$lock l
WHERE s.sid = l.sid
AND s.username IS NOT NULL
and s.sid='4125'
ORDER BY sid
;
--杀掉进程
alter system kill session'210,11562';
