Question

I am writing a multithreaded service that picks up jobs to process that has the status of 1 (unprocessed). As soon as they are picked up, I need to change the status of those rows to 2 (indicates In Progress) so that another thread (that is spawned within a few seconds) does not pick up these rows for processing.

For select, I would do something like this:

var jobs = from j in db.Jobs
           where j.Status == 1
           select j;

How do I rewrite this to update the rows and also select them at the same time?

Answer 1

Use a transaction. There are some examples of how it works here.
