Efficient API Development Database Operations in ASP.NET Core Web Using Dapper and Stored Procedures

Efficient API Development Database Operations in ASP.NET Core Web Using Dapper and Stored Procedures

When developing APIs in ASP.NET Core, efficient database operations are crucial for performance and scalability.
In this article, we will explore how to achieve efficient database operations using Dapper and Stored Procedures.

Dapper is a simple and fast micro-ORM that allows developers to execute SQL queries and map the results to
objects. It provides a lightweight alternative to Entity Framework while still offering performance benefits.

Benefits of Using Dapper

Dapper offers several benefits when compared to other ORMs like Entity Framework:

• Performance: Dapper is significantly faster than ORMs like Entity Framework due to its lightweight design
  and optimized mapping.
• Control: Developers have full control over the SQL queries and mapping logic, allowing them to fine-tune
  performance and optimize database interactions.
• Flexibility: Dapper works with any SQL database, making it a versatile choice for API development.

Using Stored Procedures

Stored procedures are precompiled database queries that can be executed from the application code. They offer
several advantages:

• Security: Stored procedures can help protect against SQL injection attacks by parameterizing input and
  preventing direct execution of user-supplied queries.
• Performance: Stored procedures are precompiled and cached on the database server, reducing query execution
  time.
• Maintainability: By centralizing database logic in stored procedures, it becomes easier to update or modify
  the database schema without affecting the application code.

To use stored procedures with Dapper, we need to define our queries and parameters using the DynamicParameters
class provided by Dapper. This allows us to easily pass input parameters and retrieve output parameters from the
stored procedure.

Implementing Efficient Database Operations

To implement efficient database operations in ASP.NET Core using Dapper and stored procedures, follow these
steps:

1. Create a connection string in your appsettings.json file to connect to the database.
2. Define your stored procedure in the database and ensure it accepts the necessary input parameters.
3. In your API controller, inject the IDbConnection interface provided by Dapper.
4. Inside the controller action method, open a connection to the database using the injected IDbConnection
   instance.
5. Create an instance of the DynamicParameters class and populate it with the necessary parameters for the
   stored procedure.
6. Execute the stored procedure using the Query or Execute methods provided by Dapper.
7. Map the results to your desired object or return the output parameters if applicable.

In conclusion, efficient API development database operations can be achieved in ASP.NET Core using Dapper and
stored procedures. By leveraging the performance benefits of Dapper and the security and maintainability
advantages of stored procedures, developers can build scalable and robust APIs.

Remember to optimize your SQL queries, use proper indexing, and regularly monitor and fine-tune your database
performance for optimal results.
