屬性值

表示這個 SyncTable 所屬之群組的 SyncGroup 物件。

備註

在定義同步處理資料表之後，可以將它加入至同步處理群組。同步處理群組是一個機制，可用來確認一組資料表中變更套用的一致性。如果資料表包含在同步處理群組中，這些資料表的變更會當做一個單位來傳輸並在單一交易中套用。如果群組中有任何變更失敗，則會在下一次同步處理時重試整個群組的變更。

範例

下列程式碼範例來自衍生自 SyncAgent 的類別。此程式碼會建立兩個同步處理群組及三個同步處理資料表。Customer 資料表會加入 Customer 群組，而 OrderHeader 和 OrderDetail 資料表會加入 Order 群組。所有的資料表僅供下載。如果用戶端上有資料表存在，則會卸除此資料表，並在初始同步處理期間重新建立。若要在完整範例的內容中檢視這段程式碼，請參閱 HOW TO：篩選資料列和資料行。

//and OrderDetail are made in one transaction. Depending on
//application requirements, you might include Customer
//in the same group.

//Add each table: specify a synchronization direction of
