Which ORM will give me compile-tested queries?

Question

Which ORM will give me compile-tested queries?

Is linqtosql compile time tested?

---

Edit:

Say I write a query that references a column named 'TotalSales'. I then rename the column in my database to TotalSales2 (and any other config file like: Employee.cfg.xml in nHibernate).
When I compile the project, I want Visual Studio to tell me the column 'totalSales' doesn't exist and then I will go and change it.

Answer 1

There aren't any as far as I'm aware. They will often let you create a LINQ query that cannot be translated into SQL for example. Also, I am not aware of any compile time checking that your mappings map to your database correctly.

You can, and should in my opinion, perform all these checks within tests. Most ORMs make this easy to do.

Answer 2

I use LLBLGen but it has to be "refreshed" when data model changes are made. I don't think you'll get an ORM that will AT COMPILE TIME check for modifications against the database. You're asking for quite a bit there.
