Question

So I have 2 entities:

Article
Category

And I have a table that relates the articleID and categoryID:

articles_categories
-articleID
-categoryID

I am using xml for my mappings, what should I do here?

I want to be able to query for all articles in a given category.

Answer 1

Use many to many mapping:

<class name="Article">     

<set name="Categories" table="articles_categories">
  <key column="ArticleId" />
  <many-to-many column="CategoryId" class="Category"  />
</set>


</class>

You should be able to query like a normal collection.
