In order to view tables of other users, you need to have the appropriate permissions. Here are some methods to view tables of other users:

  1. You can retrieve data from tables owned by other users using the SELECT statement. However, you must specify the owner’s name as a prefix, for example: SELECT * FROM other_user.table_name;
  2. Use the ALL_TABLES view: In the Oracle database, there is a system view called ALL_TABLES that contains information about all users’ tables. You can query this view to see tables owned by other users, such as: SELECT table_name FROM all_tables WHERE owner = ‘other_user’;
  3. By utilizing the DBA_TABLES view: If you have DBA-level permissions, you can query the DBA_TABLES view to see all tables of all users. For example: SELECT table_name FROM dba_tables WHERE owner = ‘other_user’;
  4. You can use the DESCRIBE statement to view the structure and column information of a table. For example: DESCRIBE other_user.table_name;

Please ensure you have sufficient permissions to perform these operations and make sure the appropriate permissions have been correctly granted before querying other users’ tables.
