我是才开始学习asp的，很多问题
最近我遇到一个问题很头痛。就是在后台添加东西如新闻。我测试了感觉只要我的内容里边含有一些符号，比如% ，* ，-等的符号，那就一定提示下边的错误，我想是否是防 sql注入的代码有问题。但看了我们自己的网站后，觉得原来我们的网站的防注入其中也有类似写法啊，所以很是头痛，请大家帮我看看。
错误提示如下：
Microsoft VBScript 编译器错误 错误 '800a03f6'
缺少 'End'
/iisHelp/common/500-100.asp，行242
Microsoft VBScript 运行时错误
缺少对象: 'killSqlconn'
/yn7cai/admin/conn.asp，行26
但在其他时候却都是正常的，这种错误只在管理员后台添加内容时候有部分符号才会出现。
这段代码是：(其中红色的就是行26了)
