Question

I have two tables, Articles and Statuses that I have associated in a ctx.dbml file.

Articles
id:int
title:varchar(255)
status_id:int

Statuses
id:int
name:varchar(255)

What I’d like to do is filter all of the articles of a certain status. Hypothetically speaking, something like:

var filteredArticles = from article in ctx.Articles
                       where article.Status.name == "Active"
                       select article;

The issue that I’m having is that in the above linq query, second line, Intellisense never gives me article.Status.name. I’ve seen code on the internet like this, so I must be missing something. Please help.

To do it like you want, you have to set up an association between the two tables.

Alternatively, you can just write the join manually.

var activeArticles = from a in ctx.Articles
                     join s in ctx.statuses on a.status_id equals s.id
                     select a;

If you go the association route, be very careful that you don’t commit the SELECT N + 1 error.
