SELECT `01` FROM perf WHERE year = '2013' order by CAST(`01` AS INT) LIMIT 3

列01的数值为varchar.我需要将'01'的前3个整数排序.为什么这个查询不起作用？

像这样的表;

+----------------------+
| name | 01 | 02 | year|
+----------------------+
|name1 | 90 |*** |2013 |
+----------------------+
|name2 | 93 | 55 |2013 |
+----------------------+
|name3 |*** | 78 |2013 |
+----------------------+

查询应按01排序(忽略*)并给出名称和值.

Uri url = new Uri("http://localhost/rgm.php");
WebClient client = new WebClient();
string html = client.DownloadString(url);

HtmlAgilityPack.HtmlDocument doc23 = new HtmlAgilityPack.HtmlDocument();
doc23.LoadHtml(html);

HtmlNode body23 = doc23.DocumentNode.SelectSingleNode("//body");

string content23 = body23.InnerHtml;

如何强制这个用"UTF-8"编码解析网页？
