An ADO Connection in ASP (Classic ASP) is established using the ADODB.Connection object. This is how your ASP page communicates with a database (like SQL Server, Access, or MySQL).

? Basic Syntax: ADO Connection in ASP

<%Dim connSet conn = Server.CreateObject("ADODB.Connection")conn.Open "your_connection_string"' Now you can execute queries using connconn.CloseSet conn = Nothing%>

? Example Connection Strings

? 1. Microsoft Access (.mdb)

conn.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.MapPath("database.mdb")

? 2. Microsoft Access (.accdb – newer format)

conn.Open "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & Server.MapPath("database.accdb")

? 3. SQL Server (Standard Login)

conn.Open "Provider=SQLOLEDB;Data Source=YOUR_SERVER;Initial Catalog=YOUR_DATABASE;User ID=USERNAME;Password=PASSWORD;"

? 4. SQL Server (Trusted Connection)

conn.Open "Provider=SQLOLEDB;Data Source=YOUR_SERVER;Initial Catalog=YOUR_DATABASE;Integrated Security=SSPI;"

? 5. MySQL (via ODBC DSN)

conn.Open "DSN=YourDSNName;UID=username;PWD=password;"

? Best Practice: Reusable DB Connection File

dbconnect.asp:

<%Dim connSet conn = Server.CreateObject("ADODB.Connection")conn.Open "your_connection_string"%>

In your pages:

<!--#include file="dbconnect.asp" -->

Would you like me to show how to run queries or insert data after the connection?
