How Can I Retrieve a List of All Tables in an Oracle Database?

Listing All Oracle Database Tables

Need a comprehensive list of all tables in your Oracle database? Here's how to do it using SQL queries:

The most straightforward approach uses the DBA_TABLES view:

<code class="language-sql">SELECT owner, table_name
FROM dba_tables;</code>

This requires appropriate database privileges. If you lack the necessary permissions, you'll need to be granted SELECT ANY DICTIONARY privilege or the SELECT_CATALOG_ROLE role to access the data dictionary.

Alternatively, if access to DBA_TABLES is restricted, use ALL_TABLES to see tables accessible to your current user account:

<code class="language-sql">SELECT owner, table_name
FROM all_tables;</code>

Keep in mind that ALL_TABLES only displays tables you have permission to view, potentially omitting some database tables.

For tables owned exclusively by your user account, employ USER_TABLES:

<code class="language-sql">SELECT table_name
FROM user_tables;</code>

USER_TABLES omits the OWNER column because the owner is implicitly your user account.

While older views like TAB and DICT exist, DBA_TABLES, ALL_TABLES, and USER_TABLES are the recommended modern views for retrieving table information.
