Publication.Remove Method ()

Removes an existing publication.

Espace de noms: Microsoft.SqlServer.Replication
Assembly: Microsoft.SqlServer.Rmo (in microsoft.sqlserver.rmo.dll)

public void Remove ()
public void Remove ()
public function Remove ()

The Remove method removes the publication and all publication metadata at the Publisher and Distributor. Use the Remove method passing a value of true to remove a publication when the Distributor is offline or cannot be accessed.

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_droppublication (Transact-SQL) or sp_dropmergepublication (Transact-SQL).

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


This example deletes a transactional publication.

// Define the Publisher, publication database, 
// and publication names.
string publisherName = publisherInstance;
string publicationName = "AdvWorksProductTran";
string publicationDbName = "AdventureWorks";

TransPublication publication;
ReplicationDatabase publicationDb;

// Create a connection to the Publisher 
// using Windows Authentication.
ServerConnection conn = new ServerConnection(publisherName);

try
{
    conn.Connect();

    // Set the required properties for the transactional publication.
    publication = new TransPublication();
    publication.ConnectionContext = conn;
    publication.Name = publicationName;
    publication.DatabaseName = publicationDbName;

    // Delete the publication, if it exists and has no subscriptions.
    if (publication.LoadProperties() && !publication.HasSubscription)
    {
        publication.Remove();
    }
    else
    {
        // Do something here if the publication does not exist
        // or has subscriptions.
        throw new ApplicationException(String.Format(
            "The publication {0} could not be deleted. " +
            "Ensure that the publication exists and that all " +
            "subscriptions have been deleted.",
            publicationName, publisherName));
    }

    // If no other transactional publications exists,
    // disable publishing on the database.
    publicationDb = new ReplicationDatabase(publicationDbName, conn);
    if (publicationDb.LoadProperties())
    {
        if (publicationDb.TransPublications.Count == 0)
        {
            publicationDb.EnabledTransPublishing = false;
        }
    }
    else
    {
        // Do something here if the database does not exist.
        throw new ApplicationException(String.Format(
            "The database {0} does not exist on {1}.",
            publicationDbName, publisherName));
    }
}
catch (Exception ex)
{
    // Implement application error handling here.
    throw new ApplicationException(String.Format(
        "The publication {0} could not be deleted.",
        publicationName), ex);
}
finally
{
    conn.Disconnect();
}

This example deletes a merge publication.

// Define the Publisher, publication database, 
// and publication names.
string publisherName = publisherInstance;
string publicationName = "AdvWorksSalesOrdersMerge";
string publicationDbName = "AdventureWorks";

MergePublication publication;
ReplicationDatabase publicationDb;

// Create a connection to the Publisher.
ServerConnection conn = new ServerConnection(publisherName);

try
{
    // Connect to the Publisher.
    conn.Connect();

    // Set the required properties for the merge publication.
    publication = new MergePublication();
    publication.ConnectionContext = conn;
    publication.Name = publicationName;
    publication.DatabaseName = publicationDbName;

    // Delete the publication, if it exists and has no subscriptions.
    if (publication.LoadProperties() && !publication.HasSubscription)
    {
        publication.Remove();
    }
    else
    {
        // Do something here if the publication does not exist
        // or has subscriptions.
        throw new ApplicationException(String.Format(
            "The publication {0} could not be deleted. " +
            "Ensure that the publication exists and that all " +
            "subscriptions have been deleted.",
            publicationName, publisherName));
    }

    // If no other merge publications exists,
    // disable publishing on the database.
    publicationDb = new ReplicationDatabase(publicationDbName, conn);
    if (publicationDb.LoadProperties())
    {
        if (publicationDb.MergePublications.Count == 0 && publicationDb.EnabledMergePublishing)
        {
            publicationDb.EnabledMergePublishing = false;
        }
    }
    else
    {
        // Do something here if the database does not exist.
        throw new ApplicationException(String.Format(
            "The database {0} does not exist on {1}.",
            publicationDbName, publisherName));
    }
}
catch (Exception ex)
{
    // Implement application error handling here.
    throw new ApplicationException(String.Format(
        "The publication {0} could not be deleted.",
        publicationName), ex);
}
finally
{
    conn.Disconnect();
