Legacy Code Example

			// Define the Publisher and publication names.
			string publisherName = publisherInstance;
			string publicationName = "AdvWorksSalesOrdersMerge";
			string publicationDbName = "AdventureWorks2012";

			// Specify article names.
			string articleName1 = "Employee";
			string articleName2 = "SalesOrderHeader";
			string articleName3 = "SalesOrderDetail";

			// Specify join filter information.
			string filterName12 = "SalesOrderHeader_Employee";
			string filterClause12 = "Employee.EmployeeID = " +
				"SalesOrderHeader.SalesPersonID";
			string filterName23 = "SalesOrderDetail_SalesOrderHeader";
			string filterClause23 = "SalesOrderHeader.SalesOrderID = " +
				"SalesOrderDetail.SalesOrderID";

			string salesSchema = "Sales";
			string hrSchema = "HumanResources";

			MergeArticle article1 = new MergeArticle();
			MergeArticle article2 = new MergeArticle();
			MergeArticle article3 = new MergeArticle();
			MergeJoinFilter filter12 = new MergeJoinFilter();
			MergeJoinFilter filter23 = new MergeJoinFilter();

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

			// Create three merge articles that are horizontally partitioned
			// using a parameterized row filter on Employee.EmployeeID, which is 
			// extended to the two other articles using join filters. 
			try
			{
				// Connect to the Publisher.
				conn.Connect();

				// Create each article. 
				// For clarity, each article is defined separately. 
				// In practice, iterative structures and arrays should 
				// be used to efficiently create multiple articles.

				// Set the required properties for the Employee article.
				article1.ConnectionContext = conn;
				article1.Name = articleName1;
				article1.DatabaseName = publicationDbName;
				article1.SourceObjectName = articleName1;
				article1.SourceObjectOwner = hrSchema;
				article1.PublicationName = publicationName;
				article1.Type = ArticleOptions.TableBased;

				// Define the parameterized filter clause based on Hostname.
				article1.FilterClause = "Employee.LoginID = HOST_NAME()";

				// Set the required properties for the SalesOrderHeader article.
				article2.ConnectionContext = conn;
				article2.Name = articleName2;
				article2.DatabaseName = publicationDbName;
				article2.SourceObjectName = articleName2;
				article2.SourceObjectOwner = salesSchema;
				article2.PublicationName = publicationName;
				article2.Type = ArticleOptions.TableBased;

				// Set the required properties for the SalesOrderDetail article.
				article3.ConnectionContext = conn;
				article3.Name = articleName3;
				article3.DatabaseName = publicationDbName;
				article3.SourceObjectName = articleName3;
				article3.SourceObjectOwner = salesSchema;

				article3.Type = ArticleOptions.TableBased;

				if (!article1.IsExistingObject) article1.Create();
				if (!article2.IsExistingObject) article2.Create();
				if (!article3.IsExistingObject) article3.Create();

				// Select published columns for SalesOrderHeader.
				// Create an array of column names to vertically filter out.
				// In this example, only one column is removed.
				String[] columns = new String[1];

				columns[0] = "CreditCardApprovalCode";

				// Remove the column.
				article2.RemoveReplicatedColumns(columns);

				// Define a merge filter clauses that filter 
				// SalesOrderHeader based on Employee and 
				// SalesOrderDetail based on SalesOrderHeader. 

				// Parent article.
				filter12.JoinArticleName = articleName1;
				// Child article.
				filter12.ArticleName = articleName2;
				filter12.FilterName = filterName12;
				filter12.JoinUniqueKey = true;
				filter12.FilterTypes = FilterTypes.JoinFilter;
				filter12.JoinFilterClause = filterClause12;

				// Add the join filter to the child article.
				article2.AddMergeJoinFilter(filter12);

				// Parent article.
				filter23.JoinArticleName = articleName2;
				// Child article.
				filter23.ArticleName = articleName3;
				filter23.FilterName = filterName23;
				filter23.JoinUniqueKey = true;
				filter23.FilterTypes = FilterTypes.JoinFilter;
				filter23.JoinFilterClause = filterClause23;

				// Add the join filter to the child article.
				article3.AddMergeJoinFilter(filter23);
			}
			catch (Exception ex)
			{
				// Do error handling here and rollback the transaction.
				throw new ApplicationException(
					"The filtered articles could not be created", ex);
			}
			finally
			{
				conn.Disconnect();
			}
