SqlSyncProvider 類別

表示與 SQL Server 資料庫通訊並讓其他 Sync Framework 元件避開資料庫之特定實作的同步處理提供者。

此 API 不符合 CLS 標準。 

命名空間：  Microsoft.Synchronization.Data.SqlServer
組件：  Microsoft.Synchronization.Data.SqlServer (在 Microsoft.Synchronization.Data.SqlServer.dll 中)

備註

同步處理提供者的主要活動如下所示：

• 儲存有關在啟用同步處理之對等項目上的資料表資訊。

• 讓應用程式能擷取自從上一次同步處理後發生在資料庫中的變更。

• 套用累加變更至資料庫。

• 偵測衝突變更。

範例

下列程式碼範例會具現化三個不同同步處理工作階段的提供者：在伺服器與 SQL Server 用戶端之間、在 SQL Server 用戶端與其中一個 SQL Server Compact 用戶端之間，以及在伺服器與其他 SQL Server Compact 用戶端之間。 其中一個 SQL Server Compact 用戶端是使用資料庫快照集來初始化。若要在完整範例的內容中檢視這段程式碼，請參閱 HOW TO：設定及執行資料庫同步處理 (SQL Server)。
