sbc.DestinationTableName = "Person";
// Number of records to be processed in one go

// Map the Source Column from DataTabel to the
Destination Columns in SQL Server 2005 Person Table
sbc.ColumnMappings.Add("PersonId", "PersonId");
sbc.ColumnMappings.Add("PersonName", "PersonName");
// Number of records after which client has to be

// Event that gets fired when NotifyAfter number of
records are processed.
sbc.SqlRowsCopied+=new
SqlRowsCopiedEventHandler(sbc_SqlRowsCopied);
