SyncParameter Constructor (String, Object)
Initializes a new instance of the SyncParameter class by using name and value parameters.
Assembly: Microsoft.Synchronization.Data (in Microsoft.Synchronization.Data.dll)
Parameters
- name
- Type: System::String
The name of the parameter.
- value
- Type: System::Object
The value of the parameter.
The following code example is from a class that derives from SyncAgent. This code creates a SyncParameter object that specifies a value for the @SalesPerson parameter. In an application, this value might come from a login ID or other user input. To view code in the context of a complete example, see How to: Filter Rows and Columns.
this.Configuration.SyncParameters.Add( new SyncParameter("@SalesPerson", "Brenda Diaz"));
Me.Configuration.SyncParameters.Add(New SyncParameter("@SalesPerson", "Brenda Diaz"))
The following code example is from a class that derives from DbServerSyncProvider. This code specifies which inserted columns and rows to download for the Customer table. You can hardcode a value for SalesPerson. However, it is more common to use a parameter that has a value that can change, as shown in the example. The example passes the filter parameter together with the other parameters that are required to download incremental inserts.
SqlCommand customerIncrInserts = new SqlCommand(); customerIncrInserts.CommandText = "SELECT CustomerId, CustomerName, CustomerType " + "FROM Sales.Customer " + "WHERE SalesPerson = @SalesPerson " + "AND (InsertTimestamp > @sync_last_received_anchor " + "AND InsertTimestamp <= @sync_new_received_anchor " + "AND InsertId <> @sync_client_id)"; customerIncrInserts.Parameters.Add("@SalesPerson", SqlDbType.NVarChar); customerIncrInserts.Parameters.Add("@" + SyncSession.SyncLastReceivedAnchor, SqlDbType.Timestamp); customerIncrInserts.Parameters.Add("@" + SyncSession.SyncNewReceivedAnchor, SqlDbType.Timestamp); customerIncrInserts.Parameters.Add("@" + SyncSession.SyncClientId, SqlDbType.UniqueIdentifier); customerIncrInserts.Connection = serverConn; customerSyncAdapter.SelectIncrementalInsertsCommand = customerIncrInserts;
Dim customerIncrInserts As New SqlCommand() With customerIncrInserts .CommandText = _ "SELECT CustomerId, CustomerName, CustomerType " _ & "FROM Sales.Customer " _ & "WHERE SalesPerson = @SalesPerson " _ & "AND (InsertTimestamp > @sync_last_received_anchor " _ & "AND InsertTimestamp <= @sync_new_received_anchor " _ & "AND InsertId <> @sync_client_id)" .Parameters.Add("@SalesPerson", SqlDbType.NVarChar) .Parameters.Add("@" + SyncSession.SyncLastReceivedAnchor, SqlDbType.Timestamp) .Parameters.Add("@" + SyncSession.SyncNewReceivedAnchor, SqlDbType.Timestamp) .Parameters.Add("@" + SyncSession.SyncClientId, SqlDbType.UniqueIdentifier) .Connection = serverConn End With customerSyncAdapter.SelectIncrementalInsertsCommand = customerIncrInserts
