SqlSyncProvider 类

表示与 SQL Server 数据库通信并将其他 Sync Framework 组件与该数据库的特定实现隔离的同步提供程序。

此类不符合 CLS。  

命名空间: Microsoft.Synchronization.Data.SqlServer
程序集: Microsoft.Synchronization.Data.SqlServer（在 microsoft.synchronization.data.sqlserver.dll 中）

语法

声明
<CLSCompliantAttribute(False)> _
Public Class SqlSyncProvider
    Inherits RelationalSyncProvider
用法
Dim instance As SqlSyncProvider

[CLSCompliantAttribute(false)] 
public class SqlSyncProvider : RelationalSyncProvider

[CLSCompliantAttribute(false)] 
public ref class SqlSyncProvider : public RelationalSyncProvider

/** @attribute CLSCompliantAttribute(false) */ 
public class SqlSyncProvider extends RelationalSyncProvider

CLSCompliantAttribute(false) 
public class SqlSyncProvider extends RelationalSyncProvider

备注

同步提供程序的主要活动如下所示：

• 存储与对等方中启用了同步的表有关的信息。

• 使应用程序能够检索自上次同步以来在数据库中发生的变更。

• 将增量变更应用于数据库。

• 检测发生冲突的变更。

示例

下面的代码示例为三个不同的同步会话实例化提供程序：这三个同步会话分别在服务器和 SQL Server 客户端之间、SQL Server 客户端和 SQL Server Compact 客户端之一之间以及服务器与另一个 SQL Server Compact 客户端之间。通过使用数据库快照对其中一个 SQL Server Compact 客户端进行初始化。若要在完整示例上下文中查看此代码，请参见如何配置和执行协作同步 (SQL Server)。

SampleSyncOrchestrator syncOrchestrator;
SyncOperationStatistics syncStats;

// Data is downloaded from the server to the SQL Server client.
syncOrchestrator = new SampleSyncOrchestrator(
    new SqlSyncProvider("filtered_customer", clientSqlConn, null, "Sync"),
    new SqlSyncProvider("filtered_customer", serverConn, null, "Sync")
    );
syncStats = syncOrchestrator.Synchronize();
syncOrchestrator.DisplayStats(syncStats, "initial");

// Data is downloaded from the SQL Server client to the 
// first SQL Server Compact client.
syncOrchestrator = new SampleSyncOrchestrator(
    new SqlCeSyncProvider("filtered_customer", clientSqlCe1Conn, "Sync"),
    new SqlSyncProvider("filtered_customer", clientSqlConn, null, "Sync")
    );
syncStats = syncOrchestrator.Synchronize();
syncOrchestrator.DisplayStats(syncStats, "initial");

// Create a snapshot from the SQL Server Compact database, which will be used to
// initialize a second Compact database. Again, this database could be provisioned
// by retrieving scope information from another database, but we want to 
// demonstrate the use of snapshots, which provide a convenient deployment
// mechanism for Compact databases.
SqlCeSyncStoreSnapshotInitialization syncStoreSnapshot = new SqlCeSyncStoreSnapshotInitialization("Sync");
syncStoreSnapshot.GenerateSnapshot(clientSqlCe1Conn, "SyncSampleClient2.sdf");

// The new SQL Server Compact client synchronizes with the server, but
// no data is downloaded because the snapshot already contains 
// all of the data from the first Compact database.
syncOrchestrator = new SampleSyncOrchestrator(
    new SqlSyncProvider("filtered_customer", serverConn, null, "Sync"),
    new SqlCeSyncProvider("filtered_customer", clientSqlCe2Conn, "Sync")
    );
syncStats = syncOrchestrator.Synchronize();
syncOrchestrator.DisplayStats(syncStats, "initial");
