Hello
[ I asked the same thing there:
http://stackoverflow.com/questions/1861537/nhibernate-how-to-retrieve-an-entity-that-has-all-entities-with-a-certain-pred]
I have an Article with a Set of Category. How can I query, using the
criteria interface, for all Articles that contain all Categories with a
certain Id?
This is not an "in", I need exclusively those who have *all* necessary
categories - and others. Partial matches should not come in there.
Currently my code is failing with this desperate attempt:
var c = session.CreateCriteria<Article>("a");
if (categoryKeys.HasItems())
{
c.CreateAlias("a.Categories", "c");
foreach (var key in categoryKeys)
c.Add(Restrictions.Eq("c", key)); //bogus, I know!
}
Anyone can give me a quick help?
