What should you do to ensure that only 10 new records are downloaded?

You create a Microsoft Windows Mobilebased application by using the Microsoft .NET Framework 3.5 and Microsoft ADO.NET. The application connects to a Microsoft SQL Server 2005 database.

The application caches data from the database server.
You write the following code segment. (Line numbers are included for reference only.)

01 public class MySyncProvider : DbServerSyncProvider{
02 public MySyncProvider (){
03 SqlConnection serverConn = new SqlConnection(“SERVER = .; Database = pubs; uid = sa;”);
04 this.Connection = serverConn;
05
06 this.BatchSize = 10;
07 }
08
09 }

You need to ensure that only 10 new records are downloaded whenever the application synchronizes.
