五种DSN的使用方法
第一种 - 这种方法用在ACCESS中最多
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
strconn = "Driver={SQL Server};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
strconn="Driver={MicrosoftAccessDriver(*.mdb)};DBQ=F:\Inetpub\wwwroot\somedir\db1.mdb;DefaultDir=f:\Inetpub\wwwroot\somedir;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
The following uses a Data Source Name:
set conn = server.createobject("adodb.connection")
conn.open "Example"
'This is created in the Control Panel using the 32 bit ODBC Driver. If you don't know how to setup here is a perfect example on ActiveServerPages.com (click here to find how to create System and File DSN's!
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
set rs = server.createobject("adodb.recordset")
rs.open "tblname", "DSNName", 3, 3
