Unanswered: selecting the schema
How to select the schema names. Will below query solve my requirement.
select distinct(owner) from all_objects;
Also is it possible to have different schema name and user name.
That query will show all schemas that contain objects.
This will show you all users, whether they own objects or not:
SQL> select username from all_users;
You can't have different schema and user names. The name of a schema is simply the name of the owner of the schema objects.
