Alo
I have a document object which can have one parent document and one
child document. A chain like this:
first version document (no parent, one child) - second version
document (one parent, one child) - third version document (one parent,
no child)
I have this mapping:
[ActiveRecord(Lazy = true)]
public class Registration
{
[BelongsTo("ParentDocumentId")]
public virtual Document ParentDocument { get; set; }
[HasMany]
public virtual IList<Document> ChildDocuments { get; set; }
public virtual Document ChildDocument
{
get
{
return ChildDocuments != null && ChildDocuments.Count
== 1 ? ChildDocuments[0] : null;
}
set
{
if (ChildDocuments == null) ChildDocuments = new
List<Document>();
ChildDocuments.Add(value);
}
}
}
How can I make a query to get the last Document (third version
document). I can't really figure out how to use HQL or criteria to
solve this problem.
Thx in advance
