The database manager implicitly grants certain privileges to a user that creates a database object such as a table or a package. Privileges are also granted when objects are created by users with DBADM authority. Similarly, privileges are removed when an object is dropped.
When the created object is a table, nickname, index, or package, the user receives CONTROL privilege on the object. When the object is a view, the CONTROL privilege for the view is granted implicitly only if the user has CONTROL privilege for all tables, views, and nicknames referenced in the view definition.
When the object explicitly created is a schema, the schema owner is given ALTERIN, CREATEIN, and DROPIN privileges WITH GRANT OPTION. An implicitly created schema has CREATEIN granted to PUBLIC.
