備註

同步處理配接器命令可讓您指定，用來從伺服器資料庫選取及套用變更的查詢和預存程序。如需詳細資訊，請參閱 HOW TO：指定快照集、下載、上傳及雙向同步處理。每一個命令都會使用同步處理期間可讓您傳遞值的工作階段變數。指定這些變數與其他參數的指定方式一樣，都是在 ADO.NET 命令中指定到查詢或預存程序中。如需詳細資訊，請參閱 HOW TO：使用工作階段變數。

範例

下列程式碼範例會在雙向及僅供上傳的同步處理案例中，建立可從 Customer 資料表刪除資料列的命令。此命令是資料庫提供者的安裝指令碼 HOW-TO 主題中所定義的預存程序。若要在完整範例的內容中檢視這段程式碼，請參閱 HOW TO：處理資料衝突和錯誤。

SqlCommand customerDeletes = new SqlCommand();
customerDeletes.CommandType = CommandType.StoredProcedure;
customerDeletes.CommandText = "usp_CustomerApplyDelete";
customerDeletes.Parameters.Add("@" + SyncSession.SyncLastReceivedAnchor, SqlDbType.Timestamp);
customerDeletes.Parameters.Add("@" + SyncSession.SyncClientId, SqlDbType.UniqueIdentifier);
customerDeletes.Parameters.Add("@" + SyncSession.SyncForceWrite, SqlDbType.Bit);           
customerDeletes.Parameters.Add("@" + SyncSession.SyncRowCount, SqlDbType.Int).Direction = ParameterDirection.Output;
customerDeletes.Parameters.Add("@CustomerId", SqlDbType.UniqueIdentifier);
customerDeletes.Connection = serverConn;
customerSyncAdapter.DeleteCommand = customerDeletes;

Dim customerDeletes As New SqlCommand()
customerDeletes.CommandType = CommandType.StoredProcedure
customerDeletes.CommandText = "usp_CustomerApplyDelete"
customerDeletes.Parameters.Add("@" + SyncSession.SyncLastReceivedAnchor, SqlDbType.Timestamp)
customerDeletes.Parameters.Add("@" + SyncSession.SyncClientId, SqlDbType.UniqueIdentifier)
customerDeletes.Parameters.Add("@" + SyncSession.SyncForceWrite, SqlDbType.Bit)
customerDeletes.Parameters.Add("@" + SyncSession.SyncRowCount, SqlDbType.Int).Direction = ParameterDirection.Output
customerDeletes.Parameters.Add("@CustomerId", SqlDbType.UniqueIdentifier)
customerDeletes.Connection = serverConn
customerSyncAdapter.DeleteCommand = customerDeletes
