Can EF4 support batch updates?

Question

Does Entity Framework v4 support batch updates/inserts so rather than sending >1 command to a db, it can send >1 command to the DB in one go?

Thanks

Answer 1

I don't believe that has changed. You have the options of:

• Stored Procedures
• Stuff like this article
• Using T-Sql like in the answer of this question

Answer 2

I discovered a good answer to this question here: Paul Welter shows how to use EntityFramework.Extended

Answer 3

I believe that can be accomplished by adding multiple Entity to the context and calling save changes.

context.ApplyChanges<T>("Order", obj1);
context.ApplyChanges<T>("Order", obj2);
context.SaveChanges();
