Removing a database deletes the database and all its objects, frees its storage allocation, and erases its entries from the sysdatabases and sysusages system tables in the master database.
drop database clears the suspect page entries pertaining to the dropped database from master..sysattributes.
You must be using the master database to drop a database.
You cannot drop a database that is in use (open for reading or writing by any user).
You cannot use drop database to remove a database that is referenced by a table in another database. Execute the following query to determine which tables and external databases have foreign-key constraints on primary key tables in the current database:
select object_name(tableid), frgndbname from sysreferences where frgndbname is not null
Use alter table to drop these cross-database constraints, then reissue the drop database command.
You cannot use drop database to remove a damaged database. Use the dbcc dbrepair command:
dbcc dbrepair (database_name, dropdb)
You cannot drop the sybsecurity database if auditing is enabled. When auditing is disabled, only the System Security Officer can drop sybsecurity.
