Remarks
Synchronization adapter commands enable you to specify the queries and stored procedures that are used to select from and apply changes to the server database. For more information, see How to: Specify Snapshot, Download, Upload, and Bidirectional Synchronization. Each command uses session variables that enable you to pass values during synchronization. These variables are specified like other parameters to queries or stored procedures in ADO.NET commands. For more information, see How to: Use Session Variables.
Examples
The following code example creates a command that selects inserted rows from the Customer table in bidirectional and download-only synchronization scenarios; and selects the table schema for initialization in all kinds of synchronization. To view this code in the context of a complete example, see How to: Handle Data Conflicts and Errors.
SqlCommand customerIncrInserts = new SqlCommand();
customerIncrInserts.CommandText =
"SELECT CustomerId, CustomerName, SalesPerson, CustomerType " +
"FROM Sales.Customer " +
"WHERE (InsertTimestamp > @sync_last_received_anchor " +
"AND InsertTimestamp <= @sync_new_received_anchor " +
"AND InsertId <> @sync_client_id)";
customerIncrInserts.Parameters.Add("@" + SyncSession.SyncLastReceivedAnchor, SqlDbType.Timestamp);
customerIncrInserts.Parameters.Add("@" + SyncSession.SyncNewReceivedAnchor, SqlDbType.Timestamp);
customerIncrInserts.Parameters.Add("@" + SyncSession.SyncClientId, SqlDbType.UniqueIdentifier);
customerIncrInserts.Connection = serverConn;
