IsDetachedPrimaryFile Method

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。

TheIsDetachedPrimaryFile method specifies whether a file is a detached primary database file.

語法

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);

備註

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.

[!附註]

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.
