Alliums. Plants in the Allium family, such as the dramatic Allium giganteum whose flower heads adorn stalks up to 6 feet tall, are regarded as a broad-spectrum natural insecticide. They repel numerous insects that plague vegetable gardens, including slugs, aphids, carrot flies and cabbage worms. Plants that will benefit from the proximity of alliums include tomatoes, peppers, potatoes, cabbage, broccoli, kohlrabi and carrots. They also will keep aphids off rose bushes.
A Login grants the principal entry into the SERVER. A User grants a login entry into a single DATABASE. Logins are a server wide (instance level) objects. Their correct name is 'server principals' (see sys.server_principals). Server wide privileges are granted to logins, like create database or view server state permissions.
Database Users are database level security principals, not server logins. Logins are given access to a database user by associating a database user with a login ID. The User then refers to the login's identity in a particular database. Additionally, all users other than SA, can be associated with one or more Roles. When a database is created, a DBO (Database Owner) Role is automatically created, which has full privileges inside the database.
