The DROP DATABASE statement physically deletes all associated database files from disk. If the database file does not exist,
or is not in a suitable condition for the database to be started, an error is generated.
DROP DATABASE cannot be used in stored procedures, triggers, events, or batches.
The database to be dropped must not be running when the DROP DATABASE statement is used. You cannot be connected to the database
you are dropping. You must be connected to a different database. For example, connect to the utility database.
You must specify a key to drop a strongly encrypted database. The key can be either a string or a variable name.
This statement is not supported on Windows Mobile.
