User Object
后续版本的 Microsoft SQL Server 将删除该功能。请避免在新的开发工作中使用该功能，并着手修改当前还在使用该功能的应用程序。
The User object exposes the attributes of a single Microsoft SQL Server database user.

注释
A database user is a security principal enabling object access permission control at the finest level of granularity. A user represents a single SQL Server login within the scope of the database in which the user is defined.
With the User object, you can:
Create a database user.
Enumerate objects owned by a user and permissions on database objects.
Remove a database user.
The Name property of a User object is a character string. Name must be a valid string for the SQL Server sysname data type and cannot include a backslash character (\).
When creating a database user by using the User object, setting the Name property is optional. If the Name property is not set, a user is created having the same name as the value specified by using the Login property.
To create a database user
Create a User object.
Set the Login property indicating an existing SQL Server login.
Set optional properties.
Add the User object to the Users collection of a connected SQLServer Database object.
A database user cannot be removed if the user owns objects in the database. With SQL Distributed Management Objects (SQL-DMO), use the Owner property to reassign database object ownership.
To remove a database user
Get the appropriate User object from the Users collection of a connected SQLServer Database object.
Use the ListOwnedObjects method of the User object to enumerate database objects owned by the user.
Use the Owner property to reassign ownership for all owned objects.
Use the Remove method of the User object to remove the database user.

The User object is compatible with instances of SQL Server versions 7.0 and later. However, the User2 object extends the functionality of the User object for use with features that were introduced in SQL Server 2000. |
