Entity Framework 6 Where in Bulk Update/Delete in one transaction

Question

In EF6, I want to update/delete bulk data in one query. My code is

 using (var context = _dataContextFactory.GetContext())
            {
                var         


        

Answer 1

You can't update multiple rows in one single SQL call with EF.

What you could do instead is to write a stored procedure that'll do the job efficiently for you. Or use a third party lib that provides extensions to EF to do it.

Of course, it won't makes sense if the number of rows to update is really small.
