无意中msgbox Ado联结字符串联结 Access connectionstring. 发现居然有这么多选择。一一分析一下。

ADO 连接Access的几种规范做法

ADO数据对象用来连接数据库的方式有两种,分别是ODBC和OLE DB方式

(一) 使用OLE DB方式
********************************************************                   
***            OLE DB Provider for Microsoft Jet
********************************************************                   
Dim oConn,strConn
Set oConn=Server.CreateObject("ADODB.Connection")
StrConn=           "Provider=Microsoft.Jet.OLEDB.4.0;" & _
                                     "Data Source=c:\somepath\myDb.mdb;" & _
                                     "User Id=admin;" & _
                                     "Password=;"
oConn.Open strConn

********************************************************
***              OLE DB Provider for ODBC Databases
********************************************************  
访问MS Access数据库
Dim oConn,strConn
Set oConn=Server.CreateObject("ADODB.Connection")
StrConn=           "Provider=MSDASQL;" & _
                                     "Driver={Microsoft Access Driver (*.mdb)};" & _
                                     "Dbq=c:\somepath\mydb.mdb;" & _
                                     "Uid=myUsername;" & _
                                     "Pwd=myPassword;"
oConn.Open strConn

(二) 使用ODBC方式
********************************************************                     
***           ODBC Driver for Access
********************************************************                     
Dim oConn,strConn
Set oConn=Server.CreateObject("ADODB.Connection")
StrConn= "Driver={Microsoft Access Driver (*.mdb)};" & _
                                     "Dbq="&Server.MapPath("Testdb.mdb"); & _
                                     "Uid=AdminAccount;" & _
                                     "Pwd=Password;"
oConn.Open strConn
