select * from dba_tables

仅当您登录的用户具有sysdba权限时，才提供所有用户的所有表。

执行以下命令:

显示Oracle数据库中的所有表

SELECT table_name FROM dba_tables;

显示当前用户拥有的表

SELECT table_name FROM user_tables;

显示当前用户可以访问的表

sql> SELECT table_name FROM all_tables

下面是一个注释的SQL查询片段，描述了如何使用选项:

-- need to have select catalog role
SELECT * FROM dba_tables;

-- to see tables of your schema
SELECT * FROM user_tables;

-- tables inside your schema and tables of other schema which you possess select grants on
SELECT * FROM all_tables;

当前用户登录模式中的表

select * from tabs;

尝试从user_tables中选择，其中列出了当前用户拥有的表。

有了这些，你可以选择:

SELECT DISTINCT OWNER, OBJECT_NAME 
    FROM DBA_OBJECTS 
    WHERE OBJECT_TYPE = 'TABLE' AND OWNER='SOME_SCHEMA_NAME';

SELECT DISTINCT OWNER, OBJECT_NAME 
    FROM ALL_OBJECTS 
    WHERE OBJECT_TYPE = 'TABLE' AND OWNER='SOME_SCHEMA_NAME';
