Files Property

项目
12/15/2008

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 Files property specifies one or more operating system files used as a database backup target or restore source.

语法

object
.Files [=value]

Parts

object
An expression that evaluates to an object in the Applies To list

value
A SQL Distributed Management Objects (SQL-DMO) multistring that identifies one or more operating system files by name

Data Type

String

Modifiable

Read/write

Prototype (C/C++)

HRESULT GetFiles(SQLDMO_LPBSTR pRetVal);
HRESULT SetFiles(SQLDMO_LPCSTR NewValue);

注意：
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.

备注

The backup medium for a backup or restore operation is specified using either the Devices, Files, Pipes, or Tapes properties. Only one medium type can be specified for any backup or restore operation, but multiple media (of the same type) may be specified.

Set the Files property to specify one or more operating system files as the backup medium. Specify more than a single operation system file to stripe the backup operation or to restore from a striped backup set.
