SQL in Code or Stored Procedures: Which Approach Offers Better Maintainability and Performance?

Is it better to embed SQL in code or store it in a stored procedure?

Several factors should be considered when deciding whether to keep SQL in C# source code or store it in a stored procedure.

Advantages of embedding SQL into code

  • Easier to maintain: Use SQL directly for query updates without the need for SQL scripts.
  • Easier to Port: No need to port stored procedures to other databases.

Advantages of stored procedures

  • Performance: Stored procedures offer potential performance improvements.
  • Security: Stored procedures can restrict database access to specific users.

Arguments against stored procedures

The answer provided questions the advantages of stored procedures:

  • Maintainability argument refuted: Stored procedures may seem easier to maintain due to the ability to update the SQL without recompiling the code. However, this perspective is limited because when significant database changes are made, the code often needs to be recompiled.
  • Reusability argument refuted: Reuse of SQL code is not unique to stored procedures. Object-relational mappers or functions in programming languages ​​provide better methods of code reuse.
  • Code Duplication: Stored procedures create code duplication, hindering maintainability and code decomposition.
  • Deployment: Updating a stored procedure requires both database and code changes, while directly embedded SQL only requires code changes.
  • Accessibility: Stored procedures are stored in a database, making them difficult to manage through a version control system.
  • Workload: Creating stored procedures for each query adds unnecessary overhead unless there is an urgent need for hierarchical or complex database logic.

Thus, the answer suggests that embedding SQL directly into C# code is a more efficient approach that provides better maintainability, portability, and code control. However, this decision should be evaluated based on specific project needs and the balance between these factors.
