AttachDBWithSingleFile2 Method

后续版本的 Microsoft SQL Server 将删除该功能。请避免在新的开发工作中使用该功能，并着手修改当前还在使用该功能的应用程序。

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

语法

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;

注释

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.

重要说明重要提示

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.

注意注意

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.
