 3          DbConnection connection  =
 4              new  SqlConnection(pubs.ConnectionString);
 5          ConnectionStringSettings bulkCopy  =
 6             ConfigurationManager.ConnectionStrings[ " BulkCopy " ];
 7          SqlConnection bulkCopyConnection  =
 8              new  SqlConnection(bulkCopy.ConnectionString);
 9          DbCommand cmd  =  connection.CreateCommand();
10          cmd.CommandType  =  CommandType.Text;
11          cmd.CommandText  =   " SELECT stor_name FROM Stores " ;
12          connection.Open();
13          bulkCopyConnection.Open();
14          DbDataReader rdr  =  cmd.ExecuteReader();
15          SqlBulkCopy bc  =   new  SqlBulkCopy(bulkCopyConnection);
16          bc.DestinationTableName  =   " StoreList " ;
17          bc.WriteToServer(rdr);
18          connection.Close();
19          bulkCopyConnection.Close();
