更新选择在LINQ to SQL [英] UPDATE SELECT in LINQ to SQL

问题描述

我写一个多线程服务，拿起作业过程中，有1（未处理）状态。一旦他们被拾起，我需要那些行的状态更改为2（表示正在进行中），这样另一个线程（即在几秒钟内生成）不拿起这些行进行处理。

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.

有关选择，我会做这样的事情：

For select, I would do something like this:

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

我如何重写这个更新行，并选择它们在同一时间？

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

推荐答案

使用交易的。还有它是如何工作这里。

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