Following section demonstrates <b>deletion with chunks</b>.
<sample>
	<pre lang="c#">
		// Table Aliases
        var t0 = new Orders().AsQueryable();
        var t1 = new OrderDetails().AsQueryable();

		// Ids are being obtained for the records to be deleted...
		var sql = Odb.SQL.Select(x => x.Fields(x[t0.OrderID]).From(t0).Top(100));
		var ids = connection.Sql(sql).Map&lt;string&gt;().ToList();

		var tasks = new List&lt;Task&gt;();
		var index = 0;
		var chunk_size = 5;
		int affected_rows = 0;

		while (true)
		{
			var items = ids.Skip(index).Take(chunk_size);
			if (items.Count() == 0) break;

			var task = Task.Run(() => {
				var query = Odb.SQL.Batch();
					query.{{hl}}Delete{{/hl}}(x => x.From(t1).Where(x[t1.OrderID].IN(items)));
					query.{{hl}}Delete{{/hl}}(x => x.From(t0).Where(x[t0.OrderID].IN(items)));

				Interlocked.Add(ref affected_rows, cn.Sql(query).NonQuery());
			});
			tasks.Add(task);
			index += items.Count;
		}

		Task.WaitAll(tasks.ToArray());
		Console.WriteLine("\n\n" + affected_rows + " row(s) affected.\n\n");
