SUMMARY

There are many ways to connect to a database. This step-by-step article provides sample connection strings for various types of databases and database connections.

Requirements

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)
  • Connectivity to a local or remote database
  • ASP enabled Microsoft Internet Explorer version 5.0 or later

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")
Cnn.open "DRIVER={Microsoft Access Driver (*.mdb)};DBQ=c:\mydatabase.mdb"
%>
				
OLE DB
<%
Set Cnn = Server.CreateObject("ADODB.Connection")
Cnn.open "PROVIDER=MICROSOFT.JET.OLEDB.4.0;DATA SOURCE=c:\mydatabase.mdb"
%>
				
File DSN
<% Set Cnn = Server.CreateObject("ADODB.Connection")
Cnn.open "FILEDSN=ADSN"
%>
				
With DSN and no User ID/Password
<%
Set Conn = Server.CreateObject("ADODB.Connection")
Conn.open "DSNname"
%>
				
With DSN and User ID/Password
<%
Set Conn = Server.CreateObject("ADODB.Connection")
Conn.open "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

OLE DB
<%
Set cnn = Server.CreateObject("ADODB.Connection")
cnn.open "PROVIDER=SQLOLEDB;DATA SOURCE=sqlservername;UID=username;PWD=password;DATABASE=mydatabase "
%>
				
With DSN
<%
Set Conn = Server.CreateObject("ADODB.Connection")
Conn.open "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"
Conn.open 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
%>
				

Oracle

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