屬性值

TableCreationOption 列舉值，這個值表示當您在用戶端資料庫中建立資料表時所要採取的動作。

備註

TableCreationOption 屬性會判斷如何在用戶端資料庫中處理資料表建立，特別是當它與資料庫中同名的現有資料表相關時。如需詳細資訊，請參閱 HOW TO：初始化用戶端資料庫及使用資料表結構描述。

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。

//Create two SyncGroups so that changes to OrderHeader
//and OrderDetail are made in one transaction. Depending on
//application requirements, you might include Customer
//in the same group.

SyncGroup orderSyncGroup = new SyncGroup("Order");

//Add each table: specify a synchronization direction of
//DownloadOnly.
SyncTable customerSyncTable = new SyncTable("Customer");
