Exemples

L'exemple suivant montre comment créer un modèle de filtre qui permette de filtrer en fonction de la colonne CustomerType de la table.

// Create a scope named "customertype_template", and add two tables to the scope.
// GetDescriptionForTable gets the schema of each table, so that tracking 
// tables and triggers can be created for that table.
DbSyncScopeDescription scopeDesc = new DbSyncScopeDescription("customertype_template");

// Set a friendly description of the template.
scopeDesc.UserDescription = "Template for Customer and CustomerContact tables. Customer data is filtered by CustomerType parameter.";

// Definition for tables.
DbSyncTableDescription customerDescription =
    SqlSyncDescriptionBuilder.GetDescriptionForTable("Sales.Customer", serverConn);
scopeDesc.Tables.Add(customerDescription);
DbSyncTableDescription customerContactDescription =
    SqlSyncDescriptionBuilder.GetDescriptionForTable("Sales.CustomerContact", serverConn);
scopeDesc.Tables.Add(customerContactDescription);

// Create a provisioning object for "customertype_template" that can be used to create a template
// from which filtered synchronization scopes can be created. We specify that
// all synchronization-related objects should be created in a 
// database schema named "Sync". If you specify a schema, it must already exist
// in the database.
SqlSyncScopeProvisioning serverTemplate = new SqlSyncScopeProvisioning(serverConn, scopeDesc, SqlSyncScopeProvisioningType.Template);
serverTemplate.ObjectSchema = "Sync";

// Specify the column in the Customer table to use for filtering data, 
// and the filtering clause to use against the tracking table.
// "[side]" is an alias for the tracking table.
// The CustomerType column that defines the filter is set up as a parameter in this template.
// An actual customer type will be specified when the synchronization scope is created.
serverTemplate.Tables["Sales.Customer"].AddFilterColumn("CustomerType");
serverTemplate.Tables["Sales.Customer"].FilterClause = "[side].[CustomerType] = @customertype";
SqlParameter param = new SqlParameter("@customertype", SqlDbType.NVarChar, 100);
serverTemplate.Tables["Sales.Customer"].FilterParameters.Add(param);

// Create the "customertype_template" template in the database.
// This action creates tables and stored procedures in the database, so appropriate database permissions are needed.
serverTemplate.Apply();

' Create a scope named "customertype_template", and add two tables to the scope.
' GetDescriptionForTable gets the schema of each table, so that tracking 
' tables and triggers can be created for that table.
Dim scopeDesc As New DbSyncScopeDescription("customertype_template")

' Set a friendly description of the template.
scopeDesc.UserDescription = "Template for Customer and CustomerContact tables. Customer data is filtered by CustomerType parameter."

' Definition for tables.
Dim customerDescription As DbSyncTableDescription = SqlSyncDescriptionBuilder.GetDescriptionForTable("Sales.Customer", serverConn)
scopeDesc.Tables.Add(customerDescription)
Dim customerContactDescription As DbSyncTableDescription = SqlSyncDescriptionBuilder.GetDescriptionForTable("Sales.CustomerContact", serverConn)
scopeDesc.Tables.Add(customerContactDescription)

Dim serverTemplate As New SqlSyncScopeProvisioning(serverConn, scopeDesc, SqlSyncScopeProvisioningType.Template)
serverTemplate.ObjectSchema = "Sync"

' Specify the column in the Customer table to use for filtering data, 
' and the filtering clause to use against the tracking table.
' "[side]" is an alias for the tracking table.
' The CustomerType column that defines the filter is set up as a parameter in this template.
' An actual customer type will be specified when the synchronization scope is created.
serverTemplate.Tables("Sales.Customer").AddFilterColumn("CustomerType")
serverTemplate.Tables("Sales.Customer").FilterClause = "[side].[CustomerType] = @customertype"
Dim param As New SqlParameter("@customertype", SqlDbType.NVarChar, 100)
serverTemplate.Tables("Sales.Customer").FilterParameters.Add(param)
