PhysicalLocation Property
未來的 Microsoft SQL Server 版本將移除這項功能。請避免在新的開發工作中使用這項功能,並規劃修改目前使用這項功能的應用程式。
The PhysicalLocation property specifies an operating system name that identifies a backup device.
語法
object.PhysicalLocation [= value]
Parts
object
An expression that evaluates to an object in the Applies To listvalue
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)
[!附註]
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.
備註
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.
