SELECT owner, TABLE_NAME FROM dba_tables
If you do not have access to
DBA_TABLES, you can see all the tables that your account has access to through the
SELECT owner, TABLE_NAME FROM all_tables
although that may be a subset of the tables available in the database (
ALL_TABLES shows you the information for all the tables that your user has been granted access to).
If you are only concerned with the tables that you own, not those that you have access to, you could use
SELECT TABLE_NAME FROM user_tables
USER_TABLES only has information about the tables that you own, it does not have an OWNER column– the owner, by definition, is you.
