问题:更新的Update语句一直在更新 卡在执行update语句的地方. 清除的方法: Oracle表死锁解除   我是在plsql中处理  1.先查询  select * from v$locked_object v, dba_objects o  where v.object_id = o.object_id    2.记录死锁表的session_id    3.Tools →Sessions  找到session_id对应Sessions窗口里的Sid(可以排下序再找比较快),在Statu…

之一: Oracle数据库操作中,我们有时会用到锁表查询以及解锁和kill进程等操作 (1)锁表查询的代码有以下的形式:select count(*) from v$locked_object;select * from v$locked_object;(2)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 =…
