How do I query an Oracle database to display the names of all tables in it?
In Oracle, you can query the data dictionary view ALL_TABLES to retrieve the names of all tables accessible to the current user. Here's a simple SQL query to accomplish this:
SELECT table_name
FROM all_tables;
This query will return a list of table names from the ALL_TABLES view. Keep in mind that ALL_TABLES includes all tables accessible to the current user, including those owned by the user as well as tables granted to the user through roles.
If you want to see only the tables owned by the current user, you can query the USER_TABLES view instead:
SELECT table_name
FROM user_tables;
This query will display only the tables owned by the current user. If you have the necessary privileges, you can also query the DBA_TABLES view to see all tables in the entire database, regardless of ownership:
SELECT table_name
FROM dba_tables;
Keep in mind that querying DBA_TABLES requires appropriate privileges. Depending on your access level, you may or may not have permission to query this view.
