oracle中锁表语句,oracle查询锁表解锁语句

一.查询锁定的表

如下语句，都可以查询锁定的表

语句一：

select a.sid,

a.serial#,

p.spid,

c.object_name,

b.session_id,

b.oracle_username,

b.os_user_name

from v$process p, v$session a, v$locked_object b, all_objects c

where p.addr = a.paddr

and a.process = b.process

and c.object_id = b.object_id

and c.OBJECT_name = ‘TABLE_NAME’;

语句二：

SELECT s.sid, s.serial#, o.object_name, s.machine

FROM gv$locked_object l, dba_objects o, gv$session s

WHERE l.object_id　 = o.object_id

AND l.session_id = s.sid

AND o.object_name = ‘TABLE_NAME’;

语句三：

SELECT l.session_id sid,

s.serial#,

l.locked_mode,

l.oracle_username,

l.os_user_name,

s.machine,

s.terminal,

o.object_name,

s.logon_time

FROM v$locked_object l, all_objects o, v$session s

WHERE l.object_id = o.object_id

AND l.session_id = s.sid

AND o.object_name = ‘TABLE_NAME’

ORDER BY sid, s.serial#;

语句四：

select a.sid,

b.serial#,

c.object_name,

decode(a.lmode,

0,

‘None’,

1,

‘Null’,

2,

‘Row-S’,

3,

‘Row-X’,

4,

‘Share’,

5,

‘S/Row-X’,

6,

‘Exclusive’,

‘Unknown’) LockMode,

B.MACHINE,

D.SPID,

b.PROGRAM

from v$lock a, v$session b, all_objects c, V$PROCESS D

where a.sid = b.sid

and a.type in (‘TM’, ‘TX’)

and c.object_id = a.id1

and B.PADDR = D.ADDR

and c.object_name = ‘TABLE_NAME’;

二.kill掉锁住的进程，解锁

–释放SESSION SQL

alter system kill session ‘SID,serial#’;
