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;

要获得所有的表名，我们可以使用:

Select  owner, table_name  from all_tables;

如果你有dba权限，你可以使用:

Select owner, table_name from dba_tables;

下面的查询只列出了所需的数据，而其他的答案给了我额外的数据，这只会让我感到困惑。

select table_name from user_tables;

查询user_tables和dba_tables无效。 这一个做到了:

select table_name from all_tables  

select * from all_all_tables

开头附加的“all”给出了额外的3列，分别是:

OBJECT_ID_TYPE
TABLE_TYPE_OWNER
TABLE_TYPE
