CopySubscriptionDatabase Method

2008-12-15

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 CopySubscriptionDatabase method copies a subscription database that has pull subscriptions, but no push subscriptions. Only single file databases can be copied.

语法

object
.CopySubscriptionDatabase(
szFileName
,
[
fOverWriteExistingFile
]
)

Parts

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

szFileName
String that specifies the complete path, including file name, to which a copy of the data portion (.mdf) file is saved.

fOverWriteExistingFile
Optional Boolean that specifies whether to overwrite an existing file of the same name specified in the szFileName parameter. The default is FALSE.

Prototype (C/C++)

HRESULT CopySubscriptionDatabase(
SQLDMO_LPCSTR pszFilename,
BOOL fOverWriteExistingFile);

备注

You can use CopySubscriptionDatabase to copy a subscription database to a file as an alternative to applying a snapshot at the Subscriber. The database must be configured to support only pull subscriptions. Users having appropriate permissions can make copies of the subscription database and then e-mail, copy, or transport the subscription file (.msf) to another Subscriber, where it can then be attached as a subscription.

This technique is useful for copying highly customized databases that contain user-defined objects, such as triggers, stored procedures, and views.

To copy a subscription database

Use the CopySubscriptionDatabase method to copy the subscription database as an .msf file.

Use the AttachSubscriptionDatabase method to attach the .msf file to the Subscriber.

注意：
If an application calls CopySubscriptionDatabase 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" are returned.
