Oracle锁表查询和解锁方法
Oracle锁表查询和解锁方法

一、首先PL/SQL要以管理员的账号（system/admin等）登录，管理员的账号和密码根据个人设置而来，连接为一般选择Normal,也可选择SYSDBA;
二、相关SQL语句：
--以下几个为相关表SELECT*FROMv$lock;SELECT*FROMv$sqlarea;SELECT*FROMv$session;SELECT*FROMv$process;SELECT*FROMv$locked_object;SELECT*FROMall_objects;SELECT*FROMv$session_wait;--查看被锁表信息SQL > select sess.sid,sess.serial#, lo.oracle_username,lo.os_user_name, ao.object_name,lo.locked_mode from v$locked_object lo,dba_objects ao,v$session sess where ao.object_id=lo.object_id and lo.session_id=sess.sid;
--杀掉锁表进程SQL > alter system kill session '68,51';--分别为SID和SERIAL#号
--查看数据库引起锁表的SQL语句 SELECT A.USERNAME, A.MACHINE, A.PROGRAM, A.SID, A.SERIAL#, A.STATUS, C.PIECE, C.SQL_TEXT FROM V$SESSION A, V$SQLTEXT C WHERE A.SID IN (SELECT DISTINCT T2.SID FROM V$LOCKED_OBJECT T1, V$SESSION T2 WHERE T1.SESSION_ID = T2.SID) AND A.SQL_ADDRESS = C.ADDRESS(+) ORDER BY C.PIECE;————————————————版权声明：本文为CSDN博主「qhzhen9」的原创文章，遵循CC 4.0 BY-SA版权协议，转载请附上原文出处链接及本声明。原文链接：https://blog.csdn.net/qq_38819293/java/article/details/86526696
