How Can I Efficiently Retrieve Query Results from Stored Procedures in Classic ASP?

Retrieving Data from Stored Procedures in Classic ASP: A Robust Approach

Classic ASP developers often encounter difficulties when retrieving data from stored procedures. The standard Execute method for ADO recordsets can produce unreliable results or fail to populate the recordset correctly. This article presents a reliable solution and best practices.

The problem typically manifests when using code like this:

<code>set rs = Server.CreateObject("ADODB.RecordSet")
rs = objCommandSec.Execute</code>

The key to resolving this lies in using the open method instead of Execute:

<code>set rs = Server.CreateObject("ADODB.RecordSet")
rs.open objCommandSec</code>

Employing the open method ensures the ADO recordset correctly connects to the stored procedure and retrieves the results.

For optimal performance and resource management, follow these guidelines:

1. Direct Database Connection: Utilize the ActiveConnection property of the ADODB.Command object to connect directly to the database. This avoids creating a separate ADODB.Connection object, streamlining resource handling and preventing leaks.

2. SET NOCOUNT ON: Ensure your stored procedure includes SET NOCOUNT ON. This prevents the procedure from returning informational messages, which can inadvertently close the recordset.

3. Array Optimization: When feasible, leverage arrays instead of ADODB.Recordsets for data manipulation. Arrays generally provide superior performance and simplified data access.

By adhering to these best practices, Classic ASP developers can reliably execute stored procedures and efficiently retrieve their results, enhancing application stability and performance.
