Should stored procedures have business logic?
“The default stance in designing an application should be that business logic is held in the application code, NOT in database stored procedures. Only move business logic into StoredProcedures as performance needs required. “
Where is business logic stored?
The business logic should be placed in the model, and we should be aiming for fat models and skinny controllers. As a start point, we should start from the controller logic. For example: on update, your controller should direct your code to the method/service that delivers your changes to the model.
Can a stored procedure have no parameters?

What is business logic in SQL?

What is the biggest drawback with stored procedures?
One of the biggest drawbacks of stored procedures is that it is extremely difficult to tell which parts of a system use them and which not.
Which is faster EF or stored procedure?
Below is my console application followed by the result. I executed the same application at least 10 times and every time, the time taken by Entity Framework is almost 3-4 times more than the time taken by a stored procedure.
What is the difference between business logic and application logic?
Business logic focuses on the information itself, while application logic defines how it happens. For example, your application logic might define what programming language to use when building software, while the business logic outlines the functions expected from the final product.
What is data logic and business logic?
The presentation logic manages the interaction with the user, the data logic handles data persistence while business logic handles the “stuff” that happens between the two. It can be difficult to precisely define what this “stuff” really means.
What is considered business logic?

Should I use stored procedures in MySQL?
We would use the stored procedures only to insert and update business model entities. There are several tables which represent a model entity, and we would abstract it in those stored procedures insert/update.

What is a stored procedure or a function?

How to avoid business logic in stored procedures?
Applications use data to do things with. Keep your data locality in mind, think about performance but try to keep business logic out of stored procedures. Where you cannot avoid business logic in stored procedures use tools and processes to help. We were unable to load Disqus.
Is it possible to have multiple sprocs in a stored procedure?
This is difficult to do with stored procedures. You may have more than one sproc dealing with the same table(s). Chaining multiple sprocs together so that the logic resides in only one gets unwieldy. That is strike one. How do you determine “What are all of the business rules surrounding entity X” within the database?
How can I run a business rule from a SQL database?
When the data is stored in SQL, you have several options: Create SQL code that will extract the results of the “business rule”. Create a user defined function that will parse and execute the business rule. Extract the data to another environment, such as C++ or C#, and run the code there. I have a bias toward the first of these.
