Hi,

I have 2 tables that have a one to many relationship. 1 table has the main data with a PK, One table has detials that contains the fk. The the details tables has a relationship to a look up table using a type field. The lookup table has an order field, type field and a description field. What I'd like to do is to order the main table by the order field in the lookup table for one of the properties in the main table mapping file. Is it possible to do this and if so, how? Any help is greatly appreciate.

Hello Liza,
sorry but I did not understand as well. You speak about two tables and in your text you have 1+1+ a referencing table.
May be you should detail your question like:
table a (
id int,
someText varchar(255),
primary key(id)
)
table b(
id int,
foreign_key_to_a int,
...

You may have a look in the Hibernate reference as well. There are quite some examples.

Best Regards Sebastian
