DropMember Method
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 DropMember method removes the specified Microsoft SQL Server user, database role, or login from the role referenced.
语法
object.DropMember(User)
Parts
object
Expression that evaluates to an object in the Applies To list.User
For the DatabaseRole object, a string that specifies an existing database user or role by name. For the ServerRole object, a string that specifies an existing SQL Server login by name.
Prototype (C/C++)
HRESULT DropMember(SQLDMO_LPCSTR NewValue);
注释
Configuring role membership by using the DropMember method of the Database and ServerRole objects requires appropriate permission.
For the Database object, the database user mapped to the SQL Server login used for SQLServer object connection must be a member of the fixed database role db_owner.
For the ServerRole object, the SQL Server login used for SQLServer object connection must be a member of the role from which the specified login will be dropped.
