Oracle查询可以有多种方法,下面为您介绍的是如何Oracle查询被锁的表及Oracle查询连接的进程的方法,希望对您能够有所帮助. 一.查看被锁的表 select p.spid,a.serial#, 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…

-- 查看被锁对象 select object_name,machine,s.sid,s.serial# from v$locked_object l,dba_objects o ,v$session s where l.object_id = o.object_id and l.session_id=s.sid; --杀死进程 alter system kill session '24,111'; (其中24,111分别是上面查询出的sid,serial# ora-00031:session…

--查询已锁的表 select request_session_id spid,OBJECT_NAME(resource_associated_entity_id) tableName ,* from sys.dm_tran_locks where resource_type='OBJECT' --解锁表(@spid) declare @spid int Set @spid = 62 --锁表进程 declare @sql varchar(1000) set @sql='kill '+cast(…

1.Oracle查询数据库中所有表的记录数,但是有可能不准建议用第二种方式进行查询 select t.table_name,t.num_rows from user_tables t 2.创建oracle函数,通过函数中查询词表记录数显示当前记录数 create or replace function count_rows(table_name in varchar2, owner in varchar2 default null) return number authid current_us…

原文地址:11g不能导出空表的多种解决方法">oracle 11g不能导出空表的多种解决方法作者:Anlin_Yang ORACLE 11g 用exp命令导出库文件备份时,发现只能导出来一部分表而且不提示错误,之前找不到解决方案只能把没导出来的表重新建建立.后来发现是所有的空表都没有导出来.于是想好好查查,因为在以前的10g版本中没有这样的问题. 查资料发现Oracle 11g中有个新特性:新增了一个参数"deferred_segment_creation"含义是段延迟…
