Introduction

ADO recordsets are a fundamental component of any web application built using Active Server Pages (ASP). In this article, we'll explore how to use RS with ASP and provide practical examples for you to follow along.

Understanding the Basics

Before diving into code, let's first understand what an ADO recordset is. An ADO recordset is a type of database object that retrieves data from a database based on a specified query. In the context of ASP, an RS (RecordSet) is used to store data retrieved from an SQL query.

Step 1: Create an OLE DB Connection

To use an ADO recordset in your ASP application, you need to establish a connection to your database. This can be done using the `Server.CreateObject` method to create an instance of the OLE DB connection object (`ADODB.Connection`). Here's how to do it: ```asp DIM DBConn Set DBConn = Server.CreateObject("ADODB.Connection") ```

Step 2: Open the Database Connection

Once you have your OLE DB connection object, you need to open the connection to your database. You can use the `Open` method of the `ADODB.Connection` object for this purpose. ```asp MdbFilePath = Server.MapPath("stores.mdb") DBConn.Open "Driver={Microsoft Access Driver (*.mdb)}; DBQ=" & MdbFilePath & ";" ```

Step 3: Execute an SQL Query

With your database connection open, you can now execute an SQL query to retrieve data from your database. You use the `Execute` method of the `ADODB.Connection` object to do this. ```asp SQL = "SELECT * FROM tblStores where Region = '" & request.querystring("region") & "'" Set RS=server.CreateObject("Adodb.recordset") RS = DBConn.execute(SQL) ```

Step 4: Loop Through the Data and Display it

Once you have your recordset object (`RS`) populated with data, you can loop through the records using a `While Not RS.EOF` loop. Here's how to display each record in an ASP page: ```asp If RS.EOF And RS.BOF Then Response.Write "There are 0 records." Else While Not RS.EOF Response.write("

" & RS("ShopName") & "

") Response.write(RS("Address1")) RS.MoveNext Wend End If ```

Conclusion

In this article, we have explored how to use an ADO recordset in ASP. We started by understanding the basics of what an RS is and then moved on to create an OLE DB connection object, open it, execute an SQL query, and finally loop through the data retrieved from the database. I hope you found this guide helpful! If you have any questions or need further clarification on any of these steps, feel free to ask.
