AttachDBWithSingleFile2 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。

The AttachDBWithSingleFile2 method makes a database visible to an instance of Microsoft SQL Server.

語法

object.AttachDBWithSingleFile2(DBName,DataFile)as Boolean

Parts

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

• DBName
  String that specifies an existing database by name.

• DataFile
  String that specifies the database PRIMARY data file by operating system file name.

Prototype (C/C++)

HRESULT AttachDBWithSingleFile2(
SQLDMO_LPCSTR DBName, 
SQLDMO_LPCSTR DataFile, 
LPBOOL pRetVal) PURE;

備註

The AttachDBWithSingleFile2 method is used when a change to the location of operating system (OS) files implementing the database must be made visible to the instance of SQL Server.

The DataFile argument specifies a single OS data file that implements storage for a SQL Server database. The instance of SQL Server creates an operating system file for transaction log record maintenance as part of the AttachDBWithSingleFile2 method processing.

The AttachDBWithSingleFile2 method returns TRUE if the attach database operation succeeds. Applications that require detailed information regarding the success or failure of the attach database operation can call the AttachDBWithSingleFile method, which returns a detailed string containing this information.

重要事項
The AttachDBWithSingleFile2 method only succeeds when storage for a database is implemented within a single operating system file. Files that implement storage for database transaction log records are not made visible by the method. For more information about making multiple databases visible to an instance of SQL Server, see AttachDB Method.

Making a database visible to an instance of SQL Server using the AttachDBWithSingleFile2 method requires appropriate permissions. The SQL Server login used for SQLServer object connection must be a member of the system-defined sysadmin role.

[!附註]

If an application calls AttachDBWithSingleFile2 on an instance of SQL Server version 7.0, the constant SQLDMO_E_SQL80ONLY and a message message similar to "This property or method requires Microsoft SQL Server 2000" are returned.
