A DROP USER statement drops a
user definition. The metadata of the user to be dropped is dropped from the catalog.Syntax
<drop_user_statement> ::= DROP USER <user_name> [<cascade_option>]
user_name, cascade_optionExplanation
The current user must have owner authorization over the user to be dropped.
The specified user must not be logged onto the database system when the DROP USER statement is executed.
Dropping a user with the
user class DBA does not affect any users that were created by this user. The SYSDBA user then becomes the new owner of these users.
