How to delete a user in oracle?

@dedrick 

To delete a user in Oracle, follow these steps:

1. Log in to SQL*Plus or any other tool you use to connect to the Oracle database.
2. Connect as a user with the necessary privileges to delete other users, such as the sys or system user.
3. Run the following SQL command to delete a user:

1

DROP USER username CASCADE;

Replace "username" with the name of the user you want to delete. The CASCADE keyword will also delete all objects owned by the user.

1. Confirm that you want to delete the user when prompted.

Note: Deleting a user is an irreversible action and will also delete all objects owned by the user. Be sure to backup any important data before proceeding with the deletion.
