Osservazioni

The Create method can be called by members of the sysadmin fixed server role at the Publisher. It can also be called by members of the db_owner fixed database role on the publication database.

Calling Create is equivalent to executing sp_addarticle (Transact-SQL) for transactional or snapshot replication or executing sp_addmergearticle (Transact-SQL) for merge replication.

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

Esempio

// Define the Publisher, publication, and article names.
string publisherName = publisherInstance;
string publicationName = "AdvWorksProductTran";
string publicationDbName = "AdventureWorks";
string articleName = "Product";
string schemaOwner = "Production";

TransArticle article;

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

// Create a filtered transactional articles in the following steps:
// 1) Create the  article with a horizontal filter clause.
// 2) Add columns to or remove columns from the article.
try
{
    // Connect to the Publisher.
    conn.Connect();

    // Define a horizontally filtered, log-based table article.
    article = new TransArticle();
    article.ConnectionContext = conn;
    article.Name = articleName;
    article.DatabaseName = publicationDbName;
    article.SourceObjectName = articleName;
    article.SourceObjectOwner = schemaOwner;
    article.PublicationName = publicationName;
    article.Type = ArticleOptions.LogBased;
    article.FilterClause = "DiscontinuedDate IS NULL";

    // Ensure that we create the schema owner at the Subscriber.
    article.SchemaOption |= CreationScriptOptions.Schema;
