Oracle删除所有表

Oracle 清理用户所有的表

PLSQL中执行语句

select 'drop '||object_type||' '||object_name||';' from user_objects;

结果集是所有的删除表语句，将查询结果保存为clear.sql

在sql>提示符下@clear.sql 执行该脚本

SQL*Plus 登录

1.直接敲sqlplus并回车就是启动SQL*PLUS，输入user及password将使用户登陆到缺省的数据库

C:\Documents and Settings\Administrator>sqlplus 

SQL*Plus: Release 9.2.0.1.0 - Production on

请输入用户名: 

2.sqlplus user/password@SERVICE_NAME将连接到指定的数据库

C:\Documents and Settings\Administrator>sqlplus dbusername/password@SERVICE_NAME
SQL*Plus: Release 9.2.0.1.0 - Production on

3.但如果敲 sqlplus /nolog就是使SQL*PLUS启动,但不登陆Oracle数据库。然后需要使用connect命令连接Oracle

C:\Documents and Settings\Administrator>sqlplus /nolog 

SQL*Plus: Release 9.2.0.1.0 - Production on
