PlSQLDeveloper工具提供了会话管理功能. 能够查询会话内容.杀死会话.查看会话SQL等操作. 常用的会话查询SQL如下: -- 查询所有会话 select * from v$session where username is not null order by logon_time, sid -- 查询用户会话 select * from v$session where username = user order by logon_time, sid -- 查询活动会话 select
最近开发项目时要经常自己造数据,遇到好多查询出数据时要进行修改.上网查询资料 总结如下: plSql允许查询数据可以编辑的条件是必须查询出rowid 在某个表上点击query data 出现的sql语句是 :select * from student t 在某个表上点击 edit data 出现的sql语句是:select t.*, t.rowid from student t 说明要编辑必须带有rowid 比如我们查询这样一条语句 select A,B from AB 让他可以编辑的办法 se

SELECT a.inst_id,sid,username,event,sql_id,a.PROGRAM FROM gv$session a WHERE a.STATUS='ACTIVE' AND username IS NOT NULL; 或者 SELECT sid,username,event,sql_id,a.PROGRAM FROM v$session a WHERE a.STATUS='ACTIVE' AND username IS NOT NULL; 注: 1.gv$session:
SELECT * FROM User_Objects t WHERE t.Object_Type IN ('PROCEDURE', 'PACKAGE BODY', 'FUNCTION') AND t.Last_Ddl_Time > SYSDATE - 1 AND t.Status = 'VALID';
