每个ASP程序员必备的知识

打开数据库：
exec=”select * from 数据库表”
set rs=server.createobject(“adodb.recordset”)
rs.open exec,conn,1,1
参数1，1为读取

读取内容格式：<%=rs(“字段”)%>

添加记录处理程序：
<%
set conn=server.createobject(“adodb.connection”)
conn.open “driver={microsoft access driver
(*.mdb)};dbq=”&server.mappath(“数据库名”)
name=request.form(“字段”)  
name,tel,message为提交表单所设置的字段值
tel=request.form(“字段”)
message=request.form(“字段”)
exec=”insert into 表名(字段)values(‘”+字段+”‘)”
多个用逗号隔开
conn.execute exec  
使用execute提交
conn.close
set conn=nothing
%>

搜索处理程序:
<%
name=request.form(“字段”) name,tel为提交表单所设置的字段值
tel=request.form(“字段”)
set conn=server.createobject(“adodb.connection”)
conn.open “driver={microsoft access driver
(*.mdb)};dbq=”&server.mappath(“数据库名”)
exec=”select * from 表 where name='”+字段+”‘ and tel=”+字段
set rs=server.createobject(“adodb.recordset”)
rs.open exec,conn,1,1
%>
‘页面搜索到的内容导出来
<%
do while not rs.eof
%><tr>
<td><%=rs(“name”)%></td>
<td><%=rs(“tel”)%></td>
<td><%=rs(“time”)%></td>
</tr>
<%
rs.movenext
loop
%>

删除记录处理程序:
<%
set conn=server.createobject(“adodb.connection”)
conn.open “driver={microsoft access driver
(*.mdb)};dbq=”&server.mappath(“数据库名”)
exec=”delete * from 表名 where 编号=”&request.form(“id”)
conn.execute exec
%>

修改记录处理程序:
<%
set conn=server.createobject(“adodb.connection”)
conn.open “driver={microsoft access driver
(*.mdb)};dbq=”&server.mappath(“数据库名”)
exec=”select * from 表名 where 编号=”&request.form(“id”)
set rs=server.createobject(“adodb.recordset”)
rs.open exec,conn,1,3  
‘1,3为修改意思
rs(“name”)=request.form(“字段”)  
‘name,tel,message为提交表单所设置的字段值
rs(“tel”)=request.form(“字段”)
rs(“message”)=request.form(“字段”)
rs.update
rs.close
set rs=nothing
conn.close
set conn=nothing
%>
修改记录执行程序:输入ID号页面>>>导出相对应ID数据>>>>>>直接修改的处理程序

后台登陆处理程序例子:
<%
dim name,password
name=request.form(“name”)
password=request.form(“password”)
dim exec,conn,rs
exec=”select *from 表名 where(name='”&字段&”‘ and
password='”&字段&”‘)”
set conn=server.createobject(“adodb.connection”)
conn.open “driver={microsoft access driver
(*.mdb)};dbq=”&server.mappath(“数据库名”)
set rs=server.createobject(“adodb.recordset”)
rs.open exec,conn
if not rs.eof then
rs.Close
conn.Close
session(“checked”)=”yes”
session(“check”)=”right”
response.Redirect “index.asp”
else
session(“checked”)=”no”
session(“check”)=”wrong”
response.Redirect “login.asp”
end if
