PhysicalName Property

В будущей версии Microsoft SQL Server эта возможность будет удалена. Избегайте использования этой возможности в новых разработках и запланируйте изменение существующих приложений, в которых она применяется.

The PhysicalName property specifies the path and file name of the operating system file storing Microsoft SQL Server database or transaction log data.

Синтаксис

object
.PhysicalName [= value]

Parts

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

  • value
    A string that specifies an operating system file

Data Type

String

Modifiable

Read/write

Prototype (C/C++)

HRESULT GetPhysicalName(SQLDMO_LPBSTR pRetVal)
HRESULT SetPhysicalName(SQLDMO_LPCSTR NewValue)
ПримечаниеПримечание

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 reference must release the reference using SysFreeString.

Замечания

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

Specify an operating system file using either drive and directory-based or Universal Naming Convention (UNC) file naming. For example, the strings "C:\Program Files\Microsoft SQL Server\Data\Northwnd.mdf" and "\\Seattle1\Program Files\Microsoft SQL Server\Data\Northwnd.mdf" are each valid for PhysicalName.
