A login is used for user authentication and a database user account is used for database access and permissions validation.

登录用于用户身份验证，而数据库用户帐户用于数据库访问和权限验证。

If no user account exists in a database for a specific login, the user that is using that login cannot access the database even though the user may be able to connect to the SQL Server server.

如果数据库中不存在针对特定登录的用户帐户，使用该登录的用户即使能够连接到SQL Server服务器，也无法访问数据库。

Login cannot become the owner of the current database if it already has access to the database through an existing alias or user security account within the database.

如果login已通过数据库内现有的别名或用户安全帐户访问了数据库，则该登录名不能成为当前数据库的所有者。
