    - You cannot roll back a DROP DATABASE statement.

    - Use the DROP DATABASE statement to drop the database.

    - This statement is useful when you want to drop a test database or drop an old database after successful migration to a new host.

    - You must have the SYSDBA system privilege to issue this statement. The database must be mounted in exclusive and restricted mode, and it must be closed.

    - Syntax
    drop_database::=

    - When you issue this statement, Oracle Database drops the database and deletes all control files and datafiles listed in the control file.

    - If the database used a server parameter file (spfile), it is also deleted.

    - Archived logs and backups are not removed, but you can use Recovery Manager (RMAN) to remove them.

    - If the database is on raw disks, this statement does not delete the actual raw disk special files.
