Drops the definition for an empty database from the data dictionary.
You must drop all the objects contained by that database before you can drop the database itself.
The drop operation verifies that the database is empty, verifies that the database does not own any other databases or users, drops the database, and adds the PERM and TEMP space that the drop makes available to that of the immediate owner database or user.
After a database is dropped, you cannot recover it by using the Dump and Restore utility unless it is restored.
You must have the DROP DATABASE privilege on the database to be dropped.
