Assembly :  Microsoft.SqlServer.Rmo (dans Microsoft.SqlServer.Rmo.dll)

Syntaxe

'Déclaration
Public Sub Remove
'Utilisation
Dim instance As Subscription

instance.Remove()
public void Remove()
public:
void Remove()

public function Remove()

Notes

The Remove method can only be called by members of the sysadmin fixed server role at the Publisher or by members of the db_owner fixed database role on the publication database.

Calling Remove is equivalent to executing sp_dropsubscription or sp_dropmergesubscription.

This namespace, class, or member is supported only in version 2.0 of the Microsoft .NET Framework.

Exemples

This example deletes a push subscription to a transactional publication.
