IsDetachedPrimaryFile Method

Dieses Feature wird in einer zukünftigen Version von Microsoft SQL Server entfernt. Verwenden Sie dieses Feature beim Entwickeln neuer Anwendungen nicht, und planen Sie das Ändern von Anwendungen, in denen es zurzeit verwendet wird.

The IsDetachedPrimaryFile method specifies whether a file is a detached primary database file.

Syntax

object
.IsDetachedPrimaryFile(
MDFName
)
as Boolean

Parts

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

MDFName
String that contains the name of the primary Microsoft SQL Server database or log file.

Prototype (C/C++)

HRESULT IsDetachedPrimaryFile(
SQLDMO_LPCSTR MDFName, 
LPBOOL pRetVal);

Hinweise

Prior to calling IsDetachedPrimaryFile, an application should call the ListDetachedDBFiles property to retrieve a complete list of detached database files or ListDetachedLogFiles property to retrieve a complete list of detached log files. The application can then call IsDetachedPrimaryFile to determine which of the files is the primary file.

Hinweis:
If an application calls IsDetachedPrimaryFile on an instance of SQL Server version 7.0, the constant, SQLDMO_E_SQL80ONLY, and the message "This property or method requires Microsoft SQL Server 2000 or later" are returned.
