Article.Create Method

Creates a new article on the currently connected instance of SQL Server based on the current properties of the TransArticle object or the MergeArticle object.

Namespace: Microsoft.SqlServer.Replication
Assembly: Microsoft.SqlServer.Rmo (in microsoft.sqlserver.rmo.dll)

Syntax

'Declaration
Public Sub Create
public void Create ()
public:
void Create ()
public void Create ()
public function Create ()

Remarks

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.

Example

// 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;

    if (!article.IsExistingObject)
    {
        // Create the article.
        article.Create();
