asp中常用的数据库连接方法介绍

作者：袖梨 2022-06-29

第一种 – 这种方法用在ACCESS中最多

 代码如下 复制代码
dim conn,strconn
strconn = “DRIVER=Microsoft Access Driver (*.mdb);DBQ=” & Server.MapPath(“aspfree.mdb”)
set conn = server.createobject(“adodb.connection”)
conn.open strconn

第二种－这种方法用在SQL SERVER中多

 代码如下 复制代码
strconn = “Driver={SQL erver};Description=sqldemo;SERVER=127.0.0.1;UID=LoginID;&_
PWD=Password;DATABASE=Database_Name
set conn = server.createobject(“adodb.connection”)
conn.open strconn

第三种

 代码如下 复制代码
strconn=”Driver={MicrosoftAccessDriver(*.mdb)};” &_
“DBQ=F:Inetpubwwwrootsomedirdb1.mdb;DefaultDir=f:Inetpubwwwrootsomedir;
&_ uid=LoginID;” &_
“pwd=Password;DriverId=25;FIL=MSAccess;”
set conn = server.createobject(“adodb.connection”)
conn.open strconn

第四种运用系统数据源

 代码如下 复制代码
The following uses a Data Source Name:
set conn = server.createobject(“adodb.connection”)
conn.open “Example”

第五种运用ODBC数据源，前提是你必须在控制面板的ODBC中设置数据源

 代码如下 复制代码
set rs = server.createobject(“adodb.recordset”)
rs.open “tblname”, “DSNName”, 3, 3
1.
set dbconnection=Server.CREATEOBJECT(“ADODB.CONNECTION”)
DBPath = Server.MapPath(“customer.mdb”)
dbconnection.Open “driver={Microsoft Access Driver (*.mdb)};dbq=” & DBPath
SQL=”select * from auth where id=”" & user_id &”"”
    SET uplist=dbconnection.EXECUTE(SQL)
2.
    set dbconnection=Server.CreateObject(“ADODB.Connection”)
    DBPath = Server.MapPath(“customer.mdb”)
dbconnection.Open “provider=microsoft.jet.oledb.4.0;data source=”&dbpath
SQL=”select * from auth where id=”" & user_id &”"”
SET uplist=dbconnection.EXECUTE(SQL)
3.
    DBPath = Server.MapPath(“customer.mdb”)
    set session(“rs”)=Server.CreateObject(“ADODB.Recordset”)
“   rs=Server.CreateObject(“ADODB.Recordset”)
connstr=”provider=microsoft.jet.oledb.4.0;data source=”&dbpath
SQL=”select * from auth where id=”" & user_id &”"”
session(“rs”).Open sql,connstr,1,3
4.
建odbc源xxx
set conn=server.createobject(“Adodb.connection”)
conn.open “DSN=xxx;UID=;PWD=;Database=customer
连

接mysql数据库

'测试读取MySql数据库的内容

 代码如下 复制代码

strconnection="driver={mysql odbc 3.51 driver};database=weste_net;server=localhost;uid=root;password="
'无需配置dsn
set adodataconn = server.createobject("adodb.connection")
adodataconn.open strconnection
