Question

What are the pros and cons of using linq queries(along with an ORM like EF or linq2sql) VS. Stored Procedures(SQL server 2008) to query and update a data model? Performance? Speed? Etc…

Answer 1

Linq is definitely more readable when you’re in the code. Seeing a call to execute a sproc called “sp_GetSomething” doesn’t tell you anything as a developer, unless you go and physically look at what the sproc does. seeing code like

var query = from c in db.TableName
            where c.Name == "foo"
            select c;

That tells you exactly what data is being pulled.

Stored procedures on the other hand do not require you to recompile the application if you decide to change the code. If you decide to suddenly change a “where” clause or change the Order By – changing a sproc is easy. Changing the Linq code could be more time consuming.

I’m sure there are plenty more, but these are two I’ve noticed.
