Why do I need Stored Procedures when I have LINQ to SQL

Question

My understanding of Linq to Sql is it will take my Linq statement and convert it into an equivalent SQL statement.

So

var products = from p in db.Product         


        

Answer 1

You certainly don't "need" stored procedures. But they can come in handy if your domain model requires a complex aggregate Entity and you don't have the luxury/flexibility to modify your database tables to fit your domain model. In this case using Linq-to-SQL or another ORM might result in a very poorly performing set of database calls to construct your Entity. A stored proc can come to the rescue here.

Of course, I would advocate using a methodology or process like TDD/BDD that provides you the flexibility to modify your database tables as needed without much pain. That's always the easier, more maintainable path in my opinion.
