Removes a database completely. If the database is open and a database name not given, it removes the current database.
DROP DATABASE [<database-name> <server-username> <server-user-password>]
<database-nameDefines the database you want to drop. By default it uses the current database, if it's open.
<server-username>Defines the server user. This user must have the privileges to drop the database.
<server-user-password>Defines the password for the server user.
NOTE: When you drop a database, it deletes the database and all records, caches and schema information it contains. Unless you have made backups, there is no way to restore the database after you drop it.
