Oracle DROP USER operator.

Preamble

Oracle DROP USER operator is used to delete a user from the Oracle database and delete all objects belonging to that user.

Syntax for the DROP USER operator in Oracle/PLSQL

DROP USER user_name [ CASCADE ];

Parameters and arguments of the operator

• user_name – The name of the user to be removed from the Oracle database.
• CASCADE – Optional. If user_name owns any objects (tables or views in its schema), you must specify CASCADE to remove all these objects.

Let’s consider a simple example DROP USER

If the user is not the owner of any objects in his scheme, you can execute the following DROP USER operator:

DROP USER Stan;

This will delete a user named ivan. The DROP USER operator will only work if ivan does not own any objects in its schema.

The user Ivan has created his objects in his schema. You will need to execute the following DROP, USER operator:

DROP USER stan CASCADE;

This DROP USER operator will delete the stan user, and remove all objects (tables and views) belonging to the ivan user, and any reference integrity restrictions on ivan user objects will also be removed.
