Oracle数据库忘记了密码如何查看数据库表数据

sqlplus / as sysdba
查看DBA用户
SQL> desc dba_users;

SQL> select username,password from dba_users order by created desc;


 

直接查某一个库的表；
SQL> select table_name from dba_tables where owner='CCS';


访问某个库表内容
SQL> select count(*) from ccs.PS_SO_SIGN_20160721;


修改用户的密码
SQL> alter user direp identified by 123456;
用户名密码访问相应库
SQL> connect direp/123456;
查询库下面的表
SQL> select table_name from user_tables;
