GetUserName 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 GetUserName method returns the database user used by the referenced login, when a connection using that login accesses the specified database.

语法

object
.GetUserName(
Database
)

Parts

• object
  Expression that evaluates to an object in the Applies To list.

• Database
  String that identifies an existing Microsoft SQL Server database by name.

Prototype (C/C++)

HRESULT GetUserName(SQLDMO_LPCSTR DatabaseName,
SQLDMO_LPBSTR pRetVal);

注意：
SQL Distributed Management Objects (SQL-DMO) strings are always returned as OLE BSTR objects. A C/C++ application obtains a reference to the string. The application must release the reference using SysFreeString.

Returns

A string that identifies a database user.

备注

The GetUserName method returns an empty string when the login specified does not have access to the database.
