All, I'm trying to create the HQL to load an entity and all its children, ordering both and I'm struggling a little. It may be possible using Critera but I must admit I find those a little hard to understand so tend to use HQL.
I have a self referencing table with data like the following ID,Name,Parent,Sequence 1, Fred, null, 0 2, Jack, 1, 0 3, Jill, 1, 1 4, Mary, 1, 2 6, Bill, null, 1 7, Murray, 6, 0 8, Katy, 6, 1 9, New York, 8, 0 10, London, 8, 1 11, Boston, 8, 2 So Fred and Bill are both roots but are sorted in sequence (0,1). They each have their own children also sorted in sequence. As you can see, the Sequence numbers are sequential within their level parent. Its possible (i.e. Katy) for the hierarchy to continue down. In my case though I am only ever going to have a maximum 3 levels (root -> child - > child). What I'm after is HQL or the criteria query that lets me load a root for an id, all the children (children A) for that root sorting those children A by Sequence, then all the children (children B) of children A sorting those Children B by sequence. I tried HQL similar to LEFT JOIN FETCH but it loads duplicate roots and I don't think I could sort Children B with this method. Any advice please - thanks. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "nhusers" group.
