问题描述:
ASP中向数据库添加记录的方法有哪几种呢？
解析:
1.用ADODB.Connection对象执行 SQL 语句 INSERT INTO
2.创建一个记录集 RS . 然后使用 RS.AddNew 方法
(这种方法比较简单并且安全，推荐)
3.通过ADODB.Command对象执行SQL
一、创建ACCESS数据库db1.mdb，在其中建立数据表user,字段分别为：u_uid（自动），u_user（用户名：文本型），u_pass(密码：文本型)
二、创建register.asp文件，此页面是添加数据的界面
<%@ language=vbscript %><html >
<head>
<title>注册页面</title>
<meta http-equiv="Content-Type" content="text/html charset=gb2312" />
<style type="text/css">
td img {display: block}.STYLE2 {font-size: 12px}
.STYLE3 {
color: #FF0000
font-weight: bold
font-size: 16px
}
</style>
</head>
<body bgcolor="#ffffff">
<table width="531" border="0" align="center" cellpadding="0" cellspacing="0">

三、建立接收register.asp中发送过来的表单数据，并插入到数据表user中的注册成功显示页面：result2.asp代码如下：
<%@ language=vbscript %><%
'字符串连接数据库的方法
set conn=server.createobject("adodb.connection")
conn.Open "DRIVER=Driver do Microsoft Access (*.mdb)uid=adminpwd=DBQ="&server.MapPath("regdb1.mdb")
%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html charset=gb2312" />
<title>注册成功</title><br>
</head>
<body>
<%
'建立recordset对象方法
set rst=server.createobject("adodb.recordset")
set rst1=conn.execute("insert into user (u_user,u_pass) values('"&request.form("u_user")&"','"&request.form("u_pass")&"')")
%>
<table width="300" border="0" align="center">
<tr>
<td align="center"><img src="chenggong.jpg" alt="注册成功" width="297" height="201"></td>
</tr>
</table>
</body>
</html>
原来是这样的：从数据库里读取用户名等于request("UserName"）的纪录，如果不为空，那么就是纪录存在，就提示已经存在这个用户，代码如下：set rs=server.createobject("adodb.recordset")
sql="select * from Cp_User where qq='"&request("UserName"）&"'"
rs.open sql,conn,1,1
if not rs.bof and rs.eof then'如果纪录不为空，则提示该用户已经存在
response.write "用户已经存在，请选择其他用户名"
response.end()
else'如果纪录不存在，则写入数据库
set rsUser=server.createobject("adodb.recordset")
sqltext="select * from Cp_User"
rsUser.open sqltext,conn,3,3
rsUser.addnew
rsUser("qq")=request("UserName")
rsUser("sj")=request("sj")
rsUser("sf")=request("sf")
rsUser.update
rsUser.close
end if
