SQL Queries: Code vs. Stored Procedures – Which Approach Offers Better Maintainability and Performance in an ASP.NET Application?

C# Code vs. Stored Procedures in ASP.NET: A Maintainability and Performance Comparison

This analysis weighs the benefits and drawbacks of embedding SQL queries directly within C# code versus utilizing SQL Server Stored Procedures (SPs) in an ASP.NET forum application.

In-Code SQL Queries: Advantages

• Simplified Maintenance: Modifying queries involves straightforward C# code adjustments, bypassing the need for separate SQL script execution and deployment.
• Enhanced Portability: Database migration to alternative systems is streamlined as no SPs need transferring or recreating.

Stored Procedures: Advantages

• Potential Performance Gains: SPs can optimize query execution through database-level enhancements.
• Improved Security: Centralized database access via SPs minimizes exposure of sensitive SQL statements.

Arguments Against Stored Procedures

The case against SPs centers on several key concerns:

• Maintenance Overhead: Updating SPs requires managing separate SQL scripts, potentially leading to unnecessary recompilation even for minor changes. This complexity can outweigh the benefits in many scenarios.
• Reusability Alternatives: C# functions or ORMs offer superior reusability compared to SPs, promoting cleaner, more maintainable code.
• Code Duplication Concerns: SPs can lead to duplicated code, contradicting modular design principles.
• Deployment Complexity: While beneficial in some multi-server deployments, most application changes impact the C# code, not the database. The overhead of deploying SP changes might not justify their use.
• Code Review Challenges: Restricted access to source control for SPs can hinder thorough code reviews.
• Unnecessary Complexity: The creation and management of numerous SPs adds unnecessary overhead with limited return on investment for many applications. The simplicity of in-code SQL often proves more efficient.
