PhysicalLocation Property

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 PhysicalLocation property specifies an operating system name that identifies a backup device.

语法

object
.PhysicalLocation [= value]

Parts

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

  • value
    A string that identifies an operating system file or tape device

Data Type

String

Modifiable

Read/write before device creation. Read-only when referencing an existing backup device.

Prototype (C/C++)

HRESULT GetPhysicalLocation(SQLDMO_LPBSTR pRetVal)
HRESULT SetPhysicalLocation(SQLDMO_LPCSTR NewValue)
注意注意

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.

注释

The PhysicalLocation property is a string with a maximum of 260 characters.

Specify an operating system file or tape using a Universal Naming Convention (UNC) string. For example, the string "\\Seattle1\Backups\Northwind.bak" specifies a server name, directory, and file name for a backup device. The string \\.\TAPE0 specifies a server and a file device, most likely a tape, as a backup device.
