asp中的各种数据库连接方法

本文收集和整理了关于Asp中数据库的各种连接方法。
(1)SQL Server数据库的连接方法
<%
url=Request.ServerVariables("QUERY_STRING") 
if instr(url,";")>=1 then 
url=Replace(url,";",";") : Response.Redirect("?" & url) 
end if 
'屏蔽通过表单攻击 
for each item in request.form 
stritem=lcase(server.HTMLEncode(Request.form(item))) 
if instr(stritem,"select ")>=1 or instr(stritem,"insert ")>=1 or instr(stritem,"update ")>=1 or instr(stritem,"delete ")>=1 or instr(stritem,"exec ")>=1 or instr(stritem,"declare ")>=1 then 
response.write ("对不起,请不要输入非法字符!") 
response.end 
end if 
next
Set conn = Server.CreateObject("ADODB.Connection")
MM_conn_STRING = "Driver={sql server};server=127.0.0.1;database=userdatabase;uid=userid;pwd=password;"
conn.open MM_conn_STRING
