Oracle数据库显示所有表的名称使用下面的查询

SELECT owner, table_name FROM dba_tables;

SELECT owner, table_name FROM all_tables;

SELECT table_name FROM user_tables;

    select object_name from user_objects where object_type='TABLE';

---------------- 或 ------------------

    select * from tab;

---------------- 或 ------------------

    select table_name from user_tables;

SELECT owner, table_name
  FROM dba_tables

This is assuming that you have access to the DBA_TABLES data dictionary view. If you do not have those privileges but need them, you can request that the DBA explicitly grants you privileges on that table, or, that the DBA grants you the SELECT ANY DICTIONARY privilege or the SELECT_CATALOG_ROLE role (either of which would allow you to query any data dictionary table). Of course, you may want to exclude certain schemas like SYS and SYSTEM which have large numbers of Oracle tables that you probably don't care about.

或者，如果您没有访问DBA_TABLES，您可以通过ALL_TABLES视图查看您的帐户访问的所有表:

SELECT owner, table_name
  FROM all_tables

不过，这可能是数据库中可用表的一个子集(ALL_TABLES显示用户已被授予访问权限的所有表的信息)。

如果你只关心你拥有的表，而不是那些你可以访问的表，你可以使用USER_TABLES:

SELECT table_name
  FROM user_tables

因为USER_TABLES只包含关于您拥有的表的信息，所以它没有OWNER列——根据定义，所有者就是您自己。

Oracle also has a number of legacy data dictionary views-- TAB, DICT, TABS, and CAT for example-- that could be used. In general, I would not suggest using these legacy views unless you absolutely need to backport your scripts to Oracle 6. Oracle has not changed these views in a long time so they often have problems with newer types of objects. For example, the TAB and CAT views both show information about tables that are in the user's recycle bin while the [DBA|ALL|USER]_TABLES views all filter those out. CAT also shows information about materialized view logs with a TABLE_TYPE of "TABLE" which is unlikely to be what you really want. DICT combines tables and synonyms and doesn't tell you who owns the object.

尝试从user_tables中选择，其中列出了当前用户拥有的表。

我找不到一个有用的答案

DBA_ALL_TABLES (ALL_ALL_TABLES/USER_ALL_TABLES)

所以决定加上我的版本。 这个视图实际上返回比DBA_TABLES更多的数据，因为它也返回对象表(http://docs.oracle.com/cd/E11882_01/server.112/e40402/statviews_1003.htm)。

为了更好地使用sqlplus查看

如果您正在使用sqlplus，您可能希望首先设置一些参数以更好地查看您的列(这些变量不应该在退出sqlplus会话后继续存在):

set colsep '|'
set linesize 167
set pagesize 30
set pagesize 1000

显示所有表格

然后你可以使用类似这样的东西来查看所有表名:

SELECT table_name, owner, tablespace_name FROM all_tables;

展示你拥有的桌子

正如@Justin Cave提到的，你可以用它来显示你拥有的表:

SELECT table_name FROM user_tables;

不要忘记视图

请记住，一些“表”可能实际上是“视图”，所以你也可以尝试运行类似的程序:

SELECT view_name FROM all_views;

结果

这应该会产生一些看起来相当可以接受的东西，比如:
