How to eager fetch a child collection while joining child collection entities to an association
- by ShaneC
Assuming the following fictional layout
Dealership
has many Cars
has a Manufacturer
I want to write a query that says get me a Dealership with a Name of X and also get the Cars collection but use a join against the manufacturer when you do so. I think this would require usage of ICriteria. I'm thinking something like this..
var dealershipQuery = Session.CreateCriteria< Dealership>("d")
.Add(Restrictions.InsenstiveLike("d.Name", "Foo"))
.CreateAlias("d.Cars", "c")
.SetFetchMode("d.Cars", FetchMode.Select)
.SetFetchMode("c.Manufacturer", FetchMode.Join)
.UniqueResult< Dealership>();
But the resulting query looks nothing like I would have expected. I'm starting to think a DetachedCriteria may be required somewhere but I'm not sure.
Thoughts?
