ASP基础

ASP与数据库-连接、写入、修改、删除、显示代码
－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
MS Access数据库连接
用DSN连接并且没有用户名和密码：
<%
set conn=Server.CreateObject("ADODB.Connection")
conn.open "YourDSNName"
%>
用DSN连接并且有用户名和密码：
<%
set conn=Server.CreateObject("ADODB.Connection")
conn.open "YourDSNName","username","password"
%>
用实际的数据库绝对路径连接：
<%
Set conn=Server.CreateObject("ADODB.Connection")
Strconn="DRIVER={Microsoft Access Driver (*.mdb)}; "
Strconn=Strconn & "DBQ=e:\yanhang\database.mdb"
conn.Open Strconn
%>
用实际的数据库相对路径连接：
<%
Set conn=Server.CreateObject("ADODB.Connection")
Strconn="DRIVER={Microsoft Access Driver (*.mdb)}; "
Strconn=Strconn & "DBQ=" & Server.MapPath("/database/yanhang.mdb")
conn.Open Strconn
%>
MS SQL Server数据库连接
用DSN连接：
<%
set conn=Server.CreateObject("ADODB.Connection")
conn.open "DSN=MyDSN;UID=user;PWD=password;DATABASE=databasename"
%>
不用DSN连接：
<%
Set conn=Server.CreateObject("ADODB.Connection")
DSNtemp="DRIVER={SQL Server};SERVER=ServerName;UID=USER;PWD=password;DATABASE=databasename"
conn.open DSNtemp
%>
Oracle数据库连接：
<%
set conn=server.createobject("adodb.connection")
conn.cursorlocation=adUseClient
DSNTemp="Provider=MSDAORA.1;Password=xxxxx;User ID=yanhang;Data Source=xxx.world"
conn.open DSNtemp
%>
数据写入

数据修改

数据删除

数据显示
……………………………………………………………………………………
<%

set rs=server.CreateObject("adodb.Recordset")
sql="Select top 20 * from News where Lei <> '"&Lei&"' order by ID desc"

暂无信息!
