squery=lcase(Request.ServerVariables("QUERY_STRING"))
sURL=lcase(Request.ServerVariables("HTTP_HOST"))
SQL_injdata =":|;|>| SQL_inj = split(SQL_Injdata,"|")
For SQL_Data=0 To Ubound(SQL_inj)
if instr(squery&sURL,Sql_Inj(Sql_DATA))>0 Then
Response.Write "您的操作可能是SQL注入行为。"
Response.end
end if
next
%>

我自己觉得还有防sql注入的方法,那就是用trim()函数,去除所有querystring过来的值的空格,因为sql执行必须带有空格哦,还有如果是id类型的判断是否为数字就OK了。
