The following are the requirements for connecting to a database:
  • Active Server Pages (ASP) enabled Internet Information Services (IIS) version 5.0 Web server with Microsoft Data Access Components (MDAC) version 2.5 or 2.6 (with a Jet database engine)

Sample Database Connection Strings

These examples are for demonstration purposes only. You must paste this code in your ASP code to make a connection to the specified database. Note that you must change elements such as database name, server name, database location, Data Source Name (DSN), and so on.

Microsoft Access

Without DSN
<%Set Cnn = Server.CreateObject("ADODB.Connection") "DRIVER={Microsoft Access Driver (*.mdb)};DBQ=c:\mydatabase.mdb"%>				
<%Set Cnn = Server.CreateObject("ADODB.Connection") "PROVIDER=MICROSOFT.JET.OLEDB.4.0;DATA SOURCE=c:\mydatabase.mdb"%>				
File DSN
<% Set Cnn = Server.CreateObject("ADODB.Connection") "FILEDSN=ADSN"%>				
With DSN and no User ID/Password
<%Set Conn = Server.CreateObject("ADODB.Connection") "DSNname"%>				
With DSN and User ID/Password
<%Set Conn = Server.CreateObject("ADODB.Connection") "DSNname","username","password"%>				
Without DSN, using a physical path as a reference
<%Set Conn = Server.CreateObject("ADODB.Connection")DSNtest="DRIVER={Microsoft Access Driver (*.mdb)}; "DSNtest=dsntest & "DBQ=c:\mydatabase.mdb" Conn.Open DSNtest%>				
Without DSN, using Server.MapPath

NOTE: Server.MapPath is the path from the Web server root. By default, this is C:\Inetpub\Wwwroot.
<%Set Conn = Server.CreateObject("ADODB.Connection")DSNtest="DRIVER={Microsoft Access Driver (*.mdb)}; "DSNtest=dsntest & "DBQ=" & Server.MapPath("/databases/mydatabase.mdb")Conn.Open DSNtest%>

Microsoft SQL Server

<%Set cnn = Server.CreateObject("ADODB.Connection") "PROVIDER=SQLOLEDB;DATA SOURCE=sqlservername;UID=username;PWD=password;DATABASE=mydatabase "%>				
With DSN
<%Set Conn = Server.CreateObject("ADODB.Connection") "DSN=MyDSN;UID=user;PWD=password;DATABASE=mydatabase"%>				
Without DSN
<%Set Conn = Server.CreateObject("ADODB.Connection")DSNtest="DRIVER={SQL Server};SERVER=ServerName;UID=USER;PWD=password;DATABASE=mydatabase" DSNtest%>

Microsoft Visual FoxPro

Without DSN
<%Set Conn = Server.CreateObject("ADODB.Connection")ConnStr= "Driver=Microsoft Visual Foxpro Driver; UID=userID;SourceType=DBC;SourceDB=C:\databases\mydatabase.dbc"Conn.Open ConnStr%>				
back to the top


<%Set Conn = Server.CreateObject("ADODB.Connection")Conn.cursorlocation=adUseClient   ' requires use of; numeric value is "DSN=test;UID=name;PWD=pass"%>				
<%Set Conn = Server.CreateObject("ADODB.Connection")Conn.cursorlocation=adUseClient   ' requires use of; numeric value is 3DSNTest="Provider=MSDAORA.1;Password=pass;User ID=name;Data" DSNtest%>
