Use drop database to remove a database from Adaptive Server, thus deleting the database and all the objects in it. This command:
Frees the storage space allocated for the database
Deletes references to the database from the system tables in the master database
Only the database owner can drop a database. You must be in the master database to drop a database. You cannot drop a database that is open for reading or writing by a user.
The syntax is:
drop database database_name [, database_name]...
You can drop more than one database in a single statement; for example:
drop database newpubs, newdb
You must drop all databases from a database device before you can drop the database device itself. The command to drop a device is sp_dropdevice.
After you drop a database, dump the master database to ensure recovery in case master is damaged.
